This KB describes a process of configuring Netwrix and SQL server to communicate via the secure channel – TLS version 1.2.
- Make sure TLS 1.2 is enabled on both servers. The easiest way to do that is using IIS Crypto software.
- Check that File version of the SQLNCLI11.DLL file located at C:\Windows\SysWOW64 and C:\Windows\System32 is 2011.110.7001.0 for both.
- If the version is lower than specified in this article – install SQL Native Client on the Netwrix server.
- Restart Netwrix Auditor Audit Archive Service
