I have a Windows 2012 server where I am getting this update as an important update. "Microsoft .NET Framework 4.6.1 for Windows Server 2012 R2 for x64 (KB3102467)".
I have a .NET MVC application on this server with Identity impersonation. When this update is installed, the identity impersonation simply stops working. The identity impersonation is connecting with the Database server which is by policy (I cannot use SQL Server authentication). I do not understand why it is causing the issue. Please help
