I recently installed, under VMware, a new Windows Server Standard 2008 R2 domain controller and joined it to my existing 2003 domain (the 2 existing domain controllers are on real hardware). One of the existing DCs and the new DC are on the same subnet at the moment. The new DC is fully patched and the 2003 servers were patched about a month ago. The install and promotion of the new DC went smooth and after the install, knowing that it was required for Exchange 2010, I promoted the forest to 2003 (the domain was at that functional level already). The next day, random PCs (all running XP SP3) around my network starting experiencing long delays when booting and arriving at the Applying Computer Settings. Granted, this new DC install and long delay could be a coincidence but I don’t think so.
I checked event logs on all DCs and the affected PCs and there’s nothing reporting any related issue. I ran an extensive, verbose DCDIAG on all the DCs and that’s attached for review. I’ve searched the Internet for other similar tales but have found nothing. My next resort, I suspect, is to use a sniffer to find out what traffic is going in/out of the PCs at this critical junction.
Has anyone heard of this issue or have any suggestions on where to start to isolate the problem? The problem is not confined to any one PC (happens across different offices) and I’ve rebooted and tried recreating it at an affected PC without luck. Is there a simple way (other than shutting down the DCs) to force PCs to go to a specific DC to try and isolate the problem.
Thank you!!!! dcdiag.txt
