CMS Evaluate Policy Error SQL Server 2014
In SQL Server Management Studio 2014 (I found the error to happen on editions up to CU5. When you use the Registered Servers tab and try and evaluate a policy you get the below error
Value cannot be null.
Parameter name: source (System.Core)
Ive tried multiple suggestions online (messing with temp folders, changing CU, nothing worked. The only solution i did find that worked is install SSMS 2016, I’ve been holding off on putting that on my workstations as RedGate SQL Prompt wasnt working with it last time i tried, but this has now been resolved as well!
