I'm having issues with Server Manager/RSAT. When I try to connect to domain servers I receive: "Configuration refresh failed with the following error: The WS-Management service cannot process the request. The computed response packet size (512103) exceeds the maximum envelope size that is allowed (512000).
I found a few other similar issues online that were resolved by increasing the WinRM max envelope size but that doesn't appear to be doing the trick for me. I get the same maximum envelope size allowed error message at 512000 no matter what I set using"winrm set winrm/config @{MaxEnvelopeSizekb="xxxx"}
