I'm trying to switch off TLS 1.0 on my SQL Server 2012 server in order to comply with PCI standards.
Initially I had some trouble with the SQL Server service not starting.
I've found help online on other sites and discussions but I'm having mixed results:
This is what I've done so far:
I have downloaded SQL Server 2012 Cumulative Update 7 (CU 6 also works) and the SQL Server Service then starts correctly.
I had a problem not being able to sign in to the DB instance through SQL Server Enterprise Manager which was fixed by installing .Net 4.6.
Next problem, client computer running IIS Application is unable to connect to SQL instance because of a 'handshaking SSL error'. I followed advice and installed the latest SNAC native client.
This was difficult to track down and the latest version available as a download from Microsoft was from 2014. I then obtained sqlnclient.msi dated 9/7/2015 revision number {E6CB4138-3D1C-4ADC-95C4-88322B60FC14} from a sub folder generated by the extract of CU 7 - "Path to Extract Folder \1033_enu_lp\x64\setup\x64".
I've updated this version of the Native client on my IIS server (and .Net 4.6) and I'm still unable to connect remotely to the SQL instance. If I enable TLS 1.0 I'm able to connect.
The exact error I'm getting is 'A connection was sucessfully established with the server, but then an error occurred during the pre-login handshake'.
My diagnosis is I don't have the correct version of SNAC on my machine compatible with TLS 1.2 and the CU 7 as the client and server cannot handshake. However, this sqlnclient.msi was extracted from the CU 7 and I cannot find a more up to date copy.
Has anyone else experienced this problem? What version of the SNAC are you using? Where did you get it?
Thanks
As of January 29th, Microsoft SQL Server supports TLS 1.2 for SQL Server 2008, SQL Server 2008 R2, SQL Server 2012 and SQL Server 2014 and major client drivers like Server Native Client, Microsoft ODBC Driver for SQL Server, Microsoft JDBC Driver for SQL Server and ADO.NET (SqlClient).
Blog post about the release: http://blogs.msdn.com/b/sqlreleaseservices/archive/2016/01/29/tls-1-2-support-for-sql-server-2008-2008-r2-2012-and-2014.aspx
List of builds that support TLS 1.2 along with the client and server component download locations (KB3135244): http://support.microsoft.com/kb/3135244
Did you get the client update from the KB (https://support.microsoft.com/en-us/kb/3052468)
Package name: 2012_SP2_SNAC_CU6_3052468_11_0_5592_x64

What is the provider name in your IIS site?
You will need the KB3052468 update both for the client and the server. They are available on the hotfix download link provided.

We are unable to send the data to SQL database using SQL adapter in BizTalk.
The error we are facing is:
error in initializing provider [DBNETLIB]ConnectionOpen(SECCreateCredentials()]SSL Security error
We have recently enabled TLS 1.2 and disabled lower versions on both BizTalk and SQL servers.
We checked that SQL server native client version 11 was also installed in both servers.
We have tried creating ODBC connection using SQL serve native client 11 and that also didn't work.
Can you please suggest what is causing the issue and any other changes needs to be implemented.
I'm trying to install Microsoft SQL Server 2017 Developer edition, cannot find one or more components, please reinstall the application is the first message and then I reinstalled the application and the error message in installation tool is Missing or unspecified settings that were configured to default values: Service SID support has been enabled on the service. Service SID support has been enabled on the service. Please help me with installing Microsoft SQL Server
I am new to SQL Server and trying to familiarize myself with it, so I have some questions.
My background is Oracle and am wondering if it works very similar to SQL Server.
On a client machine we need to install a client version of Oracle, and with the installation it comes with a TNSNames.ORA file which has settings for all of the Oracle DB's which are located on an Oracle DB server.
I would assume that SQL server would follow something similar, install a client version of SQL server? If so, does SQL Server has something similar to local Oracle?
I've found how connect to SQL server from another computer, just wondering if I still would need a slim down/client version of SQL Server, I would assume yes.

Some of you might be asking, why don't you try it, don't have my second computer yet, would like this info. ahead of time.
Thank you
SQL Server client APIs include the low-level components needed to connect to and use SQL Server so there is generally no need to install other connectivity components. To name a few Microsoft ones:
ODBC: Latest version is ODBC Driver 13.1 for SQL Server
OLE DB: Latest is SQL Server 2012 Native Client
.Net Provider for SQL Server (SqlClient): included .NET framework
JDBC: Latest Microsoft version is 6.2
There are also a number of other open source and commercial APIs available for use in various programming languages and development frameworks (e.g. Tedious for Node.js).
If I am run OLAP application in SQL installed machine (Machine A), it will work perfectly. But I need to run that application in another machine (Machine B) with Machine A's MSOLAP DLL.
Is it possible?
If yes how can I do that?
Update
I have fixed this issue by using Adomd connection instead of OleDb connection... :)
"MSOLAP.4" is the name of the OLE DB provider for Analysis Services as included with SQL Server 2008. This driver is included with the Feature Pack for SQL Server. The SQL Server 2008 Feature Pack is here. Expand the "Install instructions" header and download the correct "Microsoft SQL Server 2008 Analysis Services 10.0 OLE DB Provider" for your platform.
Since, typically, the latest versions can connect without problems to older versions, and SQL Server 2008 is no longer supported, I recommend installing the version from the SQL Server 2014 Feature Pack instead. Use "MSOLAP" as the provider name in the connection string to use the latest version rather than a specific one.
I have installed ASP .NET 2.0 MVC3, SQL server express 2005 and SQL server Management studio express 2005 and IIS 7 in my system. If I am opening the install_btnet file, and providing the SQL server details also it is not getting connect. It is giving error as Service unavailable. Any one suggest me how to install Bug tracker .NET tool in my system with examples.
Thank you.
First thing to check it that your SQL 2005 express instance is running and allowing remote connections. Open the Administrative Tools >> Services and look for the service called "MSSQLSERVER$SQLEXPRESS" and ensure it is started.
Next, open the SqlServer Configuration Utility (on the server or PC where SQL 2005 Express is Installed) Look for the Client Configuration Option and Select "Client Protocols".
Set TCP/IP to "Enabled" and you should now be able to connect to your SQL server.
Note that even if your BugTracker.NET install is on the same machine, it may still be using the network to connect to your SQL Instance.
Hope this helps,
Dave
