How to fix "Online - Data retrieval failure occurred"
Hello. I am managing a small network with 2 DC controllers. A few months ago a ransomware hit our network and encrypted all files in Sysvol. We managed to recreate Group Policies. Now I have a message from the Server Manager Dashboard belong to 2 nodes and 1 vm server saying that "Online - Data retrieval failure occurred". How can I fix this problem?
check the logs and event viewer. many resources on the net refer to corrupted registry settings.

The error message is "Invoke method error. Server: localhost, Namesapce: root\microsoft\windows\ser vermanager , Class: MSFT_ServerManager Tasks, Method: GetServerInventory, Error: Invalid namespace" Do you know how to fix this?
