Summary

When adding a new data source in the Data Source Selector, when selecting, testing connection, or applying changes to database you receive the below error:

[DBNETLIB][Connection Open (SECCreateCredentials()).]SSL Security error.

Cause

Incorrect drivers installed in order to use TLS 1.2 for SQL.

Solution

1. Ensure Microsoft ODBC Driver 11 for SQL Server is installed on the workstation, and then run the following Windows PowerShell script on the affected machine.  If it returns any red, then the incorrect drivers are installed. 

   1. Run the following script in Windows Powershell Admin

      # Helper functions to check if TLS 1.2 updates are required

      # Script currently supports checking for the following:

      # a. Check if SQL Server Native Client can support TLS 1.2

      # b. Check if Microsoft ODBC Driver for SQL Server can support TLS 1.2

      # This script is restricted to work on x64 and x86 platforms

   2. Update any drivers in RED

2. Backup and add the following registry keys

   1. Windows Registry Editor Version 5.00

      [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319]

      "SchUseStrongCrypto"=dword:00000001

      
      
      

      [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319]
