Have a network with a 2003 DC that the roles were moved to a 2008 Server... and the 2003 was never removed (and apparently something never synced completely) .. have 2012 Server running Exchange 2013.
The client got a version of crypt that infected 3 PCs and some files on the Windows 2003 server.
Had to restore the 2003 and 2008 server (or at least thought so) since there was a syncing issue of DC stuff between the 2.
Now the Exchange Server can't find the DC, get errors when attempting DC stuff on the 2008 server.
Not sure which way to go... thinking forcing all the roles to the 2008 server and forcing a removal of the 2003 server, and hoping we can get the Exchange server to like it.
Or worst case, we'll be exporting all the Exchange emails and starting the whole mess from scratch.
any tips ?
