I've introduced a new Windows 2008 R2 DC into a network having one 2003 DC w/Exchange 2003 installed on it. Everything was fine for a while but after a few reboots I can no longer use the Exchange 2010 management console.
I get: WinRM cannot process the request. The following error occured while using Kerberos authentication: The network path was not found.
My intent was to migrate everyone to the new server and remove the old one. I've migrated all the FSMO roles and mailboxes but the old server is still in the picture as a DC.
