How To Enable Tls 1.2 On Windows Server 2008 R2
First published on MSDN on Jan 29, 2016
Microsoft is pleased to announce the release of (Transport Layer Security) TLS i.2 support in all major client drivers and SQL Server releases. The updates fabricated available on January 29th, 2016 provide TLS 1.two support for SQL Server 2008, SQL Server 2008 R2, SQL Server 2012 and SQL Server 2014 . The client drivers that accept support for TLS 1.2 are SQL Server Native Client , Microsoft ODBC Commuter for SQL Server , Microsoft JDBC Driver for SQL Server and ADO.NET (SqlClient) .
The list of SQL Server server and customer component updates forth with their download locations that support TLS 1.2 is bachelor in the KB Article below:
3135244 TLS 1.two support for Microsoft SQL Server
You lot can utilize KB3135244 to download the appropriate server and client component applicable for your environment. The first build numbers that provides consummate TLS 1.two support in each major release is bachelor in KB3135244 equally well. The following tables lists the client driver/components and server components which have TLS i.2 support. Yous will demand to employ the necessary client component fixes on the server that hosts the SQL Server instance (eg. MS ODBC Commuter, SQL Server Native Customer) to ensure that the customer components installed on the server also back up TLS 1.2.
| Client Components | Server Components |
| SqlClient (.NET Framework 4.half dozen) | SQL Server 2014 |
| SqlClient (.Cyberspace Framework 4.five.ii, 4.5.1, four.5) | SQL Server 2012 |
| SqlClient (.NET Framework 4.0) | SQL Server 2008 R2 |
| SqlClient (.Cyberspace Framework 3.5/a.k.a (.Cyberspace Framework 2.0 SP2) | SQL Server 2008 |
| MS ODBC Driver v11 (Windows) | |
| SQL Server Native Client (for SQL Server 2012 & 2014) | |
| SQL Server Native Client (for SQL Server 2008 R2) | |
| SQL Server Native Client (for SQL Server 2008) | |
| SQL Server Native Customer (for SQL Server 2005) | |
| JDBC 6.0 | |
| JDBC 4.2 | |
| JDBC 4.ane | |
You can use the PowerShell script from our tigertoolbox GitHub repository to determine which client drivers on your server and client machines crave fixes.
Update: March ii, 2016 : Delight see known issue 6 for the intermittent service terminations that were reported after installing the update.
Update May 27, 2016 : Boosted fixes needed for SQL Server to utilize TLS 1.2 with Database Mail is available at KB3135244 .
Update January 31, 2017: If y'all want to check if the TLS/SSL protocol that is being used by the customer connection, then you can use the TRACE extended event (under DEBUG channel) to decide the TLS/SSL protocol, zippo, hash and peer address for the connection being made. This capability is available in SQL Server 2016 Service Pack ane and above. See KB3191296 for more details.
Outcome one
SQL Server Management Studio (SSMS), Report Server, and Report Manager don't connect to the database engine after you apply the set for SQL Server 2008, 2008 R2, 2012, or 2014. Report Server and Report Managing director fail and render the following error message:
The report server cannot open a connection to the report server database. A connexion to the database is required for all requests and processing. (rsReportServerDatabaseUnavailable)
This result occurs because SSMS, Report Manager, and Reporting Services Configuration Manager employ ADO.Internet, and ADO.Net back up for TLS 1.two is available but in the .NET Framework 4.6. For before versions of the .NET Framework, you lot accept to employ a Windows update and so that ADO.Internet can support TLS one.2 communications for the client. The Windows updates that enable TLS one.ii support in before versions of .NET framework are listed in the table in the "How to know whether you need this update" department of KB3135244.
Issue two: Reporting Services fails to start
Reporting Services Configuration Manager reports the following fault message even later on client providers have been updated to a version that supports TLS 1.2:
Could non connect to server: A connection was successfully established to the server, but so an mistake occurred during the pre-login handshake.
To resolve this problem, manually create the following registry primal on the arrangement that hosts the Reporting Services Configuration Manager:
HKEY_LOCAL_MACHINE\Organisation\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.two\Client : REG_DWORD=Enabled, "Enabled"=dword:00000001
Outcome iii: Encrypted endpoint communication fails
The encrypted endpoint communication that uses TLS 1.2 fails when you use encrypted communications for Availability Groups or Database Mirroring or Service Broker in SQL Server. An error message that resembles the following is logged in the SQL Fault log:
Connection handshake failed. An Bone call failed: (80090331) 0x80090331(The client and server cannot communicate, because they practise non possess a common algorithm.). State 56.
For more than information about this issue, come across Gear up: The encrypted endpoint communication with TLS one.2 fails when you use SQL Server .
(Update: February 22, 2016) Known Issue: If yous are on a currently using Cumulative Update for SQL Server 2014 and need to use TLS 1.2 for encrypted endpoints for features like Availability Groups, Database Mirroring or Service Broker, so we recommend that you lot install Cumulative Update 1 for SQL Server 2014 Service Pack 1 or Cumulative Update viii for SQL Server 2014 which adds back up for this particular scenario. This is documented as a known issue in KB3135852 .
Outcome 4: Encrypted communication with DBM/AG fails
An encrypted connection with Database Mirroring or Availability Groups does not work when yous utilize a certificate later yous disable all other protocols other than TLS i.2. An mistake bulletin that resembles the following is logged in the SQL Server Error log:
Connexion handshake failed. An Bone call failed: (80090331) 0x80090331(The customer and server cannot communicate, because they do not possess a common algorithm.). Land 58.
In that location might exist additional errors that you might meet in the event logs associated with this issue as shown below.
Log Name: System Source: Schannel Appointment: iii/four/2016 2:09:28 AM Effect ID: 36888 Task Category: None Level: Error Keywords: User: Organization Clarification: A fatal warning was generated and sent to the remote endpoint. This may effect in termination of the connection. The TLS protocol divers fatal fault lawmaking is 40. The Windows SChannel error state is 1205.
Log Proper noun: Organisation Source: Schannel Engagement: 3/four/2016 2:09:28 AM Outcome ID: 36874 Task Category: None Level: Error Keywords: User: System Description: An TLS 1.2 connection request was received from a remote client application, but none of the zip suites supported by the customer application are supported by the server. The SSL connexion request has failed.
Issue v : SQL Server Setup fails
SQL Server setup fails when TLS 1.2 is enabled
When yous try to install Microsoft SQL Server 2012 or SQL Server 2014 on a server that has Transport Layer Security (TLS) version one.ii enabled, you may encounter the following issues:
- If the version of SQL Server that you're trying to install doesn't incorporate the fix to enable TLS 1.2 back up, you receive the following mistake message:Look on the Database Engine recovery handle failed. Check the SQL Server error log for potential causes.
- If the version of SQL Server that you're trying to install does contain the set up to enable TLS 1.2 support, you receive the following error bulletin:A connection was successfully established with the server, but then an mistake occurred during the pre-login handshake. (provider: Named Pipes Provider, error: 0 - No process is on the other end of the pipe.)In both of these situations, the installation fails.Please refer KB3135769 for the workaround for the effect.
Event 6: Intermittent Service Termination
The following SQL Server database engine versions are affected by the intermittent service termination event that is reported in KB3146034 . For customers to protect themselves from the service termination issue, nosotros recommend that they install the TLS one.ii updates for Microsoft SQL Server that are mentioned in this commodity if their SQL Server version is listed in the following table.
| SQL Server release | Afflicted version |
| SQL Server 2008 R2 SP3 (x86 and x64) | x.l.6537.0 |
| SQL Server 2008 R2 SP2 German democratic republic (IA-64 only) | 10.l.4046.0 |
| SQL Server 2008 R2 SP2 (IA-64 simply) | 10.50.4343.0 |
| SQL Server 2008 SP4 (x86 and x64) | ten.0.6543.0 |
| SQL Server 2008 SP3 GDR (IA-64 only) | x.0.5544.0 |
| SQL Server 2008 SP3 (IA-64 simply) | ten.0.5894.0 |
Issue seven: Database Postal service does not work
Database Mail does not work with TLS 1.2
Database Mail fails with the following errors:
Agent Log:
Microsoft.SqlServer.Direction.SqlIMail.Server.Common.BaseException:
Mail configuration information could not exist read from the database.
….
….
Unable to offset mail session.
Meet the department " Boosted fixes needed for SQL Server to employ TLS one.two " in KB3135244 .
Issue 8: SQL Server service does not showtime
You get the following error after disabling all other protocols except TLS 1.two on the server while trying to starting time the SQL Server database engine service.
Error: 17182, Severity: 16, State: 1.
TDSSNIClient initialization failed with error 0x139f, condition code 0x1. Reason: Initialization failed with an infrastructure fault. Bank check for previous errors. The group or resource is not in the correct land to perform the requested operation.
Could not start the network library considering of an internal error in the network library. To decide the cause, review the errors immediately preceding this i in the error log.
Error: 17120, Severity: 16, Country: i.
SQL Server could not spawn FRunCM thread. Cheque the SQL Server error log and the Windows effect logs for data about possible related problems.
The higher up errors are reported because the SQL Server customer driver fixes were not applied on the server. Delight refer KB3135244 and utilize the applicable client driver fixes on the server.
A recording of the TLS ane.2 session delivered the Security Virtual Affiliate for Laissez passer is available beneath.
