Thanks for the info, hopefully I can fix this then we can migrate to something less brittle.

We're not keen on demoting the Exchange server (restored) either so will try demoting the DC2 and clearing the registry key...I think I'll try it in a virtual environment first. Erik - did it work for you? I’m in the same scenario as Erik as we had a hardware failure and the DR restore resulted in Event ID 2095.

DC1 with Exchange = USN 100 DC2 without exchange = USN 10 You are demoting DC2 along with cleaning the metabase since you cannot demote DC1 because of exchange and then editing the registry on DC1 with the information supplied by Rob...right? This then fixes the netlogon pausing problem when starting up DC1 Thanks for everyone for contributing! Just to clarify the steps everyone is taking here…

DC1 with Exchange = USN 100

Tried removing the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NTDS\Parameters “Dsa Not Writable”=dword:00000004″ And it worked! Saved me many hours of frustration! I was getting ready to camp on the MS line. Never gotten anything solved in less than 4 hours with them. What we all really need is a supported way from Microsoft to restore a windows server to radically different hardware. Disasters happen and you can't always restore to like system. Moving Novell Netware to new hardware is a piece of cake. And NDS is more robust. SBS complicates things becasue EVERYTHING is on one server, DC, PDC, DNS, etc. We restored an SBS2003 server for a client and the System state restored caused the USN symptomswith NETLOGON paused.
