Microsoft SQL Server Native Client 11.0 is installed when you install SQL Server 2016 (13.x). There is no SQL Server 2016 Native Client. For more information, see. You can also get sqlncli.msi from the SQL Server 2012 Feature Pack web page.
To download the most recent version of the the SQL Server Native Client, go to. If a previous version of SQL Server Native Client earlier than SQL Server 2012 is also installed on the computer, SQL Server Native Client 11.0 will be installed side-by-side with the earlier version. The SQL Server Native Client files (sqlncli11.dll, sqlnclir11.rll, and s11chsqlncli.chm) are installed to the following location:%SYSTEMROOT% system32.
Microsoft is pleased to announce the release of (Transport Layer Security) TLS 1.2 support in all major client drivers and SQL Server releases. The updates made available on January 29th, 2016 provide TLS 1.2 support for SQL Server 2008, SQL Server 2008 R2, SQL Server 2012 and SQL Server 2014. The client drivers that have support for TLS 1.2 are SQL Server Native Client, Microsoft ODBC Driver for SQL Server, Microsoft JDBC Driver for SQL Server and ADO.NET (SqlClient).
The list of SQL Server server and client component updates along with their download locations that support TLS 1.2 is available in the KB Article below: TLS 1.2 support for Microsoft SQL Server You can use to download the appropriate server and client component applicable for your environment. The first build numbers that provides complete TLS 1.2 support in each major release is available in as well. The following tables lists the client driver/components and server components which have TLS 1.2 support. You will need to apply the necessary client component fixes on the server that hosts the SQL Server instance (eg. MS ODBC Driver, SQL Server Native Client) to ensure that the client components installed on the server also support TLS 1.2. I have installed the TLS1.2 patch for 2008 R2 and installed.Net Framework 4.6.
The SQL services no longer start up automatically. (set to Automatic via services) and I cannot connect via SSMS to the instance. I can connect via the command prompt.
When I enable TLS 1.0 on the sever via the registry setting I can connect to the instance via SSMS. Error I receive is “Pre-Login handshake” error “No process is on the other end of the pipe” It appears this hotfix might not support the disabling of TLS 1.0 connectivity. Thanks for the status update.
Installation Of Microsoft Sql Server Native Client Failed Because A Higher Version
I installed the 2008 R2 SP3 based hotfix 489678ENUx64 (sqlncli.msi). I disabled SSL 3.0 and TLS 1.0 in the registry and enabled TLS 1.2. The SQL service will not start.
Event log says: “TDSSNIClient initialization failed with error 0x139f, status code 0x80. Reason: Unable to initialize SSL support. The group or resource is not in the correct state to perform the requested operation.” However, have I installed the server component at all? Or have you removed it from the hotfix package? (per your Feb-13 message) Of course if you removed it then me disabling all protocols besides TLS 1.2 will obviously cause it not to work. Can you kindly clarify the situation? Additionally, when to expect a working hotfix for 2008 R2 SP3?
I applied this update to our SQL 2008 instance on the 12th and have now uninstalled it. We have seen Issues with the instance when under load. The SQL services stopped responding. This error in the event log: SQL Server Assertion: File:, line=2760 Failed Assertion = ‘pvb-FInUse ’. This error may be timing-related.
If the error persists after rerunning the statement, use DBCC CHECKDB to check the database for structural integrity, or restart the server to ensure in-memory data structures are not corrupted. Then later loads of information entries in the event log: New queries assigned to process on Node 0 have not been picked up by a worker thread in the last 60 seconds. Blocking or long-running queries can contribute to this condition, and may degrade client response time. Use the “max worker threads” configuration option to increase number of allowable threads, or optimize current running queries. SQL Process Utilization: 0%%. System Idle: 99%%. This issue occurs because SSMS, Report Manager, and Reporting Services Configuration Manager use ADO.NET, and ADO.NET support for TLS 1.2 is available only in the.NET Framework 4.6.
For earlier versions of the.NET Framework, you have to apply a Windows update so that ADO.NET can support TLS 1.2 communications for the client. The Windows updates that enable TLS 1.2 support in earlier versions of.NET framework are listed in the table in the “How to know whether you need this update” section of. The path that you installed only updates the SQL Server Native Client. You will also need to install the client driver update for “ Microsoft ODBC Driver for SQL Server“.
Hello Amit, I have SQL server 2008 R2 Ent insalled on Windows server 2008 R2 Ent. I am unable to login to SQL server locally after the installation. Getting below error: Connection handshake failed.
An OS call failed: (80090331) 0x80090331(The client and server cannot communicate, because they do not possess a common algorithm.). The error led me to this article and I updated my DB engine to.0. But still unable to login. What should I do in order to allow my SSMS to connect locally. Adding more details to my earlier comment: I have SQL server 2008 R2 Ent insalled on Windows server 2008 R2 Ent.
I am unable to login to SQL server locally after the installation. Getting below error: Connection handshake failed. An OS call failed: (80090331) 0x80090331(The client and server cannot communicate, because they do not possess a common algorithm.). The error led me to this article and I updated my DB engine to.0. But still unable to login.
What should I do in order to allow my SSMS to connect locally. Also the second issue is SQL agent service is not starting. It fails with below error: Agent could not be started ( unable to connect to server (local), SQLserveragent cannot start). How to fix this as well?
Below is my environment details: Windows server 2008 R2 Ent. SP1 SQL Server 2008 R2 Ent (.0).Net version 4.5.51209 SCHANNEL registry status: SSL 2.0: Client: DisabledByDefault = 1 Enabled = 0 Server: DisabledByDefault = 1 Enabled = 0 SSL 3.0: Client: DisabledByDefault = 1 Enabled = 0 Server: DisabledByDefault = 1 Enabled = 0 TLS 1.0: Client: DisabledByDefault = 0 Enabled = 1 Server: DisabledByDefault = 0 Enabled = 1 TLS 1.1: Client: DisabledByDefault = 0 Enabled = 1 Server: DisabledByDefault = 0 Enabled = 1 TLS 1.2: Client: DisabledByDefault = 0 Enabled = 1 Server: DisabledByDefault = 0 Enabled = 1 Please let me know if you need any further details. Update: I made some progress on it. I installed.Net version 4.6.01055 and ADO.NET – SqlClient (.NET Framework 3.5/.NET Framework 2.0 SP2) referring link. I am now able to connect SQL server using SSMS locally and also able to start SQL agent service.
But now the new issue is appearing. I can’t connect the server remotely using windows authentication. I get below errors in windows eventviewer logs when I try to connect it. Also, no errors in SQL server error logs. Log Name: System Source: Schannel Event ID: 36888 Task Category: None Level: Error Keywords: User: SYSTEM Description: The following fatal alert was generated: 40. The internal error state is 1205.
Log Name: System Source: Schannel Event ID: 36874 Task Category: None Level: Error Keywords: User: SYSTEM Description: An TLS 1.0 connection request was received from a remote client application, but none of the cipher suites supported by the client application are supported by the server. The SSL connection request has failed. Enter image description here. We have SQL Server instance where we turned off TLS 1.0 after following all the necessary updates under KB3135244.
We are able to connect locally and remotely to the instance without any issues using SSMS. However, we have an issue running any reports on a remote SSRS to the instance running on TLS 1.2.
The connection is successful in SSMS, SQL Data Tools, and even Report Builder. Once deployed to the SSRS server, we receive the following error: A connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: TCP Provider, error: 0 – An existing connection was forcibly closed by the remote host.) What are we missing? When previewing the report in SQL Data Tools or Report Builder, it works fine. Once deployed to SSRS and ran through the SSRS web-based GUI, the data source test fails giving the error above. The SSRS server is running SQL Server & SSRS running SQL Server 2012 (11.0.6523),.NET Framework 4.6.1, SNAC 11.0.6523 (based on KB315244) on Windows 2012 R2 The data source in the report is running SQL Server 2014 with TLS 1.0 is disabled also on Windows 2012 R2 Testing the same connection from the SSRS server to the Data Source using a.udl connection gives the error: ConnectionOpen (SECDoClientHandshake). SSL Security error.
Test connection failed because of initializing provider. I would like to add that this is not environment specific to the servers mentioned above. Testing this same behavior on different SSRS servers and Data Sources running with TLS 1.0 disabled, produces the same results. Have Microsoft confirmed that SSRS can connect via the SSRS web GUI to data sources running with TLS 1.0 disabled? Both our DEV and QA DB Servers are SQL Server 2008 R2 SP3 and Windows 2012 R2, up to date on all Windows Updates. DEV Server: – SQL Server 2008 R2 SP3 TLS 1.2 Update — Installed successfully — No other actions needed QA Server – SQL Server 2008 R2 SP3 TLS 1.2 Update — Installed successfully — Attempting to connect gave the following error: “A connection was successfully established with the server, but then an error occurred during the login process. (provider: SSL Provider, error: 0 – An existing connection was forcibly closed by the remote host.)” – Installed Hot Fix, Windows8.1-KB3106993-x64 — Same result – Installed update to “Microsoft ODBC Driver for SQL Server” — “A connection was successfully established with the server, but then an error occurred during the pre-login process.
(provider: TCP Provider, error: 0 – An existing connection was forcibly closed by the remote host.)” – Uninstalled all updates at this point to revert to working QA server Do I now need to try again and go down the route of modifying the registry settings? Hardly ideal if the roll-out to our production cluster fails similar to QA? Have I ask other options Amit? Hi Amit, We are using SSMS at the moment to test our connection. When I installed the SQL Server 2008 R2 SP3 TLS 1.2 Update, the version of SQL Server went from.0 to.0. The hot fix for SQL Server Native Client (for SQL Server 2008 R2) applies to an earlier SQL Server version of.0 and would not install due to this. The MS ODBC drivers hot fix to v11 did install as did the update to.NET Framework 2.0.
However, the updates to both.NET Framework 4.0 and 4.5 did not install saying they did not apply to the computer. The OS is Windows Server 2012 R2. If your Native Client is on the build 6542, then you are on the latest build. If you need to install only the client driver update for client machines, then you need to download the appropriate client driver from the client drivers hotfix link in the second table in KB3135244. If you connection is failing with SSMS, then it needs the.NET update.
You need the.NET fix from as SSMS for older releases of SQL Server does not use.NET 4.0. Another option to check if TLS 1.2 connection is working is: 1. Verify if the SQL Server database engine starts after disabling all protocols except TLS 1.2. I am assuming this is working based on your comments. Install the latest SSMS from and check if that is able to connect to the database engine 3.
Install the.NET fix that I mentioned above. Hi Amit, We ran the installer again for KB3144114 on our QA database server and again it was successful. This time however, we were able to log in locally and remotely and it looks like everything has gone smoothly this time. This is good of course but a little strange and leaves us in a worrying situation deploying the update to our production cluster nodes. Will update here hopefully after we have deployed out the update successfully ? Thanks for your assistance and feedback. Link download film twilight saga new moon. It was very helpful.
Hi Amit, thanks for the post. I have a server with 2012 R2. I installed the SQL Server management studio SP 1 CU6.Net version is 4.5.51650 according to HKEYLOCALMACHINE SOFTWARE Microsoft NET Framework Setup NDP v4 Full 1033 I have the problem that the SQL Server management studio says that the connection was forcibly closed by the remote host. On other servers, when I installed.net 4.6, the issue was resolved. On the particular server, however, I cannot install.Net 4.6. The update which is suggested by for.Net 4.5.2 cannot be installed on my machine. It says that that version is not applicable to that machine.
What else should I do to be able to connect with the SQL Server Management Studio 2014 via TLS 1.2? Thanks KR Chris. So if anyone else has a similar problem, the following registry settings enable TLS 1.1 and 1.2 support by default for the.net framework 4-4.5, which SQL 2012 uses. By adding these the webservice task/http connection manager for SSIS can again connect to a https site that only supports TLS 1.1 or 1.2. For reference this worked with server 2012 running SQL 2012. HKEYLOCALMACHINE SOFTWARE Microsoft.NETFramework v4.0.30319 “SchUseStrongCrypto”=dword:00000001 HKEYLOCALMACHINE SOFTWARE Wow6432Node Microsoft.NETFramework v4.0.30319 “SchUseStrongCrypto”=dword:00000001. Understood, we did have TLS 1.1 and 1.2 enabled at the server level per your note.
Can you help explain why installing 4.6.1.net framework didn’t resolve the issue? 4.6.1 has TLS 1.1 and 1.2 enabled by default and after disabling TLS 1.0 on the SQL server our windows 8.1 clients couldn’t connect to SQL until.net 4.6.1 or this HF for 4.5.x was installed. Either option enables TLS 1.2 support in the.net 4.x framework but again, installing 4.6.1 DID NOT fix the web service connection problem.
I would have thought it would given your comments about SSIS using the.net components outside the control of SQL. Also surprised it’s causing my DB mail issue I commented on below. We have 4.6.1 installed and the registry fix mentioned here but database mail it’s still failing to connect to SQL.
Further I’ve VERY curious to know why disabling TLS 1.0 impacts connections to SQL that are NOT encrypted. Ok, we have another issue I have no fix for. After installing the needed SP/CUs to enable TLS 1.2 support and DISABLING TLS 1.0 on the server (due to security requirements) Databasemail no longer functions. We get this error in the application event logs. Any help to resolve would be appreciated. Seems like Microsoft hasn’t fully vetted all SQL components for TLS 1.2 support regardless of these patches.
1) Exception Information Exception Type: Microsoft.SqlServer.Management.SqlIMail.Server.Common.BaseException Message: There was an error on the connection. Reason: A connection was successfully established with the server, but then an error occurred during the pre-login handshake. We ended up fixing the issue. Had to install the.net 3.5 hotfix for the ADO.net SQL client. There needs to be a matrix of OS/SQL/.net/etc versions that tells users exactly which patches are required for FULL TLS 1.2 support across all SQL components.
I’ve never seen a “packaged” product update that has so many external dependencies. From a client/user point of view, just installing the SQL patch on the server should have been enough. If not the install should look for the other “required” patches and alert the user if they aren’t installed.
Again, seems like this was a little rushed to market. Philip: Thank you for your feedback. We have added all the fixes required to make TLS 1.2 work at A user can choose to install multiple client driver and side-by-side.NET versions on a Server/Client machine. Depending on what you have installed on your client and server machines, you will have to install the appropriate components. Not all the component fixes mentioned here are SQL components.
![]()
Some of these are.NET components which are used by Web Servers and Client OS which are not shipped as part of the Database Engine. The patch that you install for SQL Server only patches server components like Database Engine, Reporting Services, Analysis Services, Integration Services. There has been no change in our deployment and packaging in this regard for this update.

Reporting Services error information: DBNETLIBConnectionOpen (SECDoClientHandshake).SSL Security error. a case with MS support was opened but the engineer is rooming around the same hotfix things so far since a week now. They got the logs but seems not checked so far. We are having very strange problem with our production cluster after installing SP2, CU1 (5511) on SQL Server 2014. Operation Systems is Windows Server 2012 R2. Every morning we not able to connect to SQL server via SSMS remotely or locally.
Error message saying “Connection Timeout Expired. The timeout period elapsed while attempting to consume the pre-login handshake ackhnowledgement. This could be because the pre-login handshake failed or the server was unable to respond back in time” if I try from my PC running SSMS. When I login to server running SQL Server and try connecting a bit different error: “A connection was successfully established with the server, but then an error occurred during the pre-login handshake.” All SQL Services seem to be running. TCP, port enabled.
Rebooting/restarting the SQL Service resolves the issue and it works smoothly until next morning. Noticed that if I don’t do anything everything works fine after a while (in 1 hour max). The problem is only with one node of active-active cluster. Second node works fine. Interchanging the roles in cluster shows that the problem is only with one node.
We have identical test cluster environment where everything also works fine. All software versions are identical. I noticed that we have this problem after applying last SQL patch and Windows Security Update. Tried rollback to previous patch level of SQL and Windows with no luck. Any advice on this would be appreciated. Hi Amit, We are using SQL200R2, I have enabled TLS 1.2 for both Server and Client in the registry editor. Also I have installed KB3144114 and KB3099845 from KB3135244.

If TLS 1.0 is disabled I am getting below error message in SSMS “A connection was successfully established with the server, but then an error occured during the pre-login handshake. (provider: shared memory provider, error:0 – No process is on the other end of pipe.) (Microsoft SQL Server, Error: 233). I wasn’t able to update SQL server native client because its saying the current version is a higher version,.0 Can you please give suggestion what should I do to get SSMS works with TLS 1.2? Hello, I have an instance on a windows 10 (previously windows 8.1 but I experienced the same problem on that OS) for which I systematically have to enable FIPS compatible algorithm in my local security policy in order to get a valid connection to my SQL server from ODBC. My SQL instance is an SQL Server Express 2014 SP1 for x86 (version 12.1.14491.0). If I enable FIPS140 compatible algorithms, everything works fine but if I disable it I got a connection failed error ————————— Microsoft SQL Server Login ————————— Connection failed: SQLState: ‘01000’ SQL Server Error: 772 MicrosoftODBC SQL Server DriverTCP/IP SocketsConnectionOpen (SECDoClientHandshake).

Hello Amit, Thanks for your reply. I did a quick test trying to narrow down the issue here since, indeed, the registery keys have the right values.
I try, from the ODBC data source administrator tool to configure datasources with the different drivers connecting to the database while the encryption is enforced on the server itself: – ODBC Driver 11 for SQL Server (2014.120.4491.00) works fine without FIPS activated – SQL Server Native Client 11.0 (2011.110.6518.00) works fine without FIPS – SQL Server Native Client 10.0 (2007.100.2531.00) requires the activation of FIPS – SQL Server (3.00) requires FIPS – SQL Native Client (20.00) requires FIPS. After discussing with the developer in charge of this application, it seems that he does not know for sure which driver is called, though he knows he still makes use of the MSAD026.tlb based library to handle the communication with the database engine.
I think the problem must lie somewhere here and that this needs to be changed to ADO.NET to fix the problem. Thanks for your answers though! Regards, Francois.
The script tells me I do not need to update SQL, but we are on SQL 2008 R2 SP2 ( when confirming via @@version), but it’s reading in the script. Can you please advise? We restricted to TLS1.2 successfully for IIS server communicating to the SQL server, but are encountering issues with another IIS server that also has SSRS (all on Windows 2008 R2). IIS works, SSRS does not.
Applied ADO.NET hotfix as instructed, and SSRS still fails. Trying to determine best path forward. Can you advise? Hi Amit, I read whole blog, your presentation and all Microsoft documentations. After all I have question regarding relationship between SCHANNEL registry configuration and Windows Server 2008 R2. You wrote on slide 9 that Windows Server 2008 R2 provide TLSv1.2, but it is disabled by default, and we MUST configure SCHANNEL to enable it.
Microsoft wrote the same for Windows Server 2008 R2 SP1. But, I succeed to establish connection over TLS1.2, without “TLS 1.2” folder in SCHANNEL configuration, between: Client (machine 1): SQL Server Management Studio 2014 Server (machine 2): SQL Server 2014 SP2 on Windows Server 2008 R2 SP1 I monitored this communication with Microsoft Network Monitor, and I found regular Client Hello, Server Hello, and rest of comunication via TLS 1.2 (Without explicit SCHANNEL configuration). HOW IS IT POSSIBLE? Where I am wrong? Microsoft also wrote that this TLS 1.2 is provided, but disabled by default on Windows Server 2008 R2 and Windows Server 2008 R2 SP1. I produced the same on two different environments. Great presentation in any case.
Hello Amit, We need to disable TLS 1.0 in our production environment, which consists of several web and database servers. I have read the above information and below I have tried to list the procedure in points, please confirm if this is correct. Web Server: Managed Hosting server, host mix of many.net 3.5,.net 4 websites (Windows Server 2012 R2). 1) Backup the registry before enforcing use of TLS 1.2.
HKEYLOCALMACHINE SOFTWARE Microsoft.NETFramework HKEYLOCALMACHINE SOFTWARE Wow6432Node Microsoft.NETFramework 2) Force all.net applications to use TLS 1.2 by making below registry changes. HKEYLOCALMACHINE SOFTWARE Microsoft.NETFramework v4.0.30319 “SchUseStrongCrypto”=dword:00000001 HKEYLOCALMACHINE SOFTWARE Wow6432Node Microsoft.NETFramework v4.0.30319 “SchUseStrongCrypto”=dword:00000001 3)Enable the support for.net framework 3.5 and earlier versions to use operationg system default Protocols. HKEYLOCALMACHINE SOFTWARE Microsoft.NETFramework v2.0.50727 “SystemDefaultTlsVersions”=dword:00000001 HKEYLOCALMACHINE SOFTWARE Wow6432Node Microsoft.NETFramework v2.0.50727 “SystemDefaultTlsVersions”=dword:00000001 4) Install SQL Server Natice Client SQL 2012 5) Install.net patches: ADO.NET – SqlClient (.NET Framework 4.5.2, 4.5.1, 4.5) ADO.NET – SqlClient (.NET Framework 4.0) ADO.NET – SqlClient (.NET Framework 3.5/.NET Framework 2.0 SP2) 6) Disable TLS 1.0, using HKEYLOCALMACHINE SYSTEM CurrentControlSet Control SecurityProviders SCHANNEL Protocols 1.0 client and server Enabled 0. Database Server: Hosting multiple databases for multiple websites, receiving SSMS connections and connections from websites hosted on above mentioned web server.
1) First check if your MSSQL Server version support TLS 1.2 OR not by visting below link. Check if your MSSQL version is in the list?
How to know whether you need this update If not as in my case MSSQL 2012, SP3 CU 6-GDR (KB3194724)11.0.6567 you are good to DISABLE TLS 1.0 from the registry. If your MSSQL VERSION is in the list for example:.0 then you need to install the patch mentioned in Download links for earlier installs. It would be a great help for me if you confirm that the above mentioned steps are suffiecent to achieve disabling TLS 1.0 SUPPORT and forcing tls 1.2 on web and database environment.
Regards, Fahad. Using SQL Server 2012 SP3 SSRS on Windows 2008 R2 SP1 with.NET Framework 4.6. Report Manager and Report Service are installed on web server and Reports and ReportsTemp DB’s on SQL server. Using custom app to display reports. Trying to disable TLS 1.0 on web server.
App consumes Report Service and displays reports fine. Can browse to Report Service. SSMS is able to connect to Reporting Services on web server and databases on SQL server. Problem is with browsing to Report Manager on web server. Receive “Error The underlying connection was closed: An unexpected error occurred on a receive.” error on Report Manager Home page, “System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a receive. — System.ComponentModel.Win32Exception: The client and server cannot communicate, because they do not possess a common algorithm” error in the ReportServerService log and the following 15 entries in the System event log for the next 25 seconds after the request: “Source: SChannel EventID: 36871 Level: Error – A fatal error occurred while creating an SSL client credential. The internal error state is 10013.”.
I am duplicating this condition on at least two identical web servers configured the same. I have PCT 1.0, SSL 2.0, SSL 3.0, and TLS 1.0 DisabledByDefault=1 and Enabled=0 and TLS 1.1, TLS 1.2 DisabledByDefault=0 and Enabled=1 for both Client and Server in registry; downloaded and installed SP3 CU1 and all updates and client drivers including,NET and ODBC that would run and still receiving error. Have read all articles and blogs I can find and have not found anything that sounds similar since SSMS and Report Server Service are working. Not sure what to try next.
Any suggestions would be greatly appreciated. Amit, How can I download the updates/ hotfixes for the client components? In another post, you suggested to apply the hotfixes for sql 2014 RTM, but I couldn’t these fixes in sql 2014 rtm feature pack?
SQL14RTMQFECU8sqlncli SQL14RTMQFECU8msodbcsql And clicking on the links under client components in is taking to the download page of the respective components. Can you guide me as to how I can download the hotfixes for client components (native client, odbc/ jdbc drivers) for sql 2012 (sp3+) and sql 2014 (sp1+)? I have a classic ASP app that is talking (on the same box) to SQL Server 2008 10.0.6547. After disabling TLS 1.0 and applying all server/client/driver patches I was only able to connect by creating a System DSN with ODBC Driver. Could not connect with SQLNCLI10 The problem there is that the application fails because of issues with datetime fields ( see ). Is there a way to get the SQLNCLI10 provider working without TLS 1.0? I’ve modified client registry keys as suggested here, and updated to latest version of sql native driver per hotfix SQL2008SP4CODSNACx641033.
