I am trying to rename a domain in a single domain controller environment running server 2003. I have run all the commands with no errors until I get to fixing the GPO links:
gpfixup /olddns:tottenham.int /newdns:spurs.local /oldnb:tottenham /newnb:spurs /dc:dc01.spurs.local /user:administrator /pwd:password 2>1 > gpfixup.log
At that point from the control station, I get a cryptunprotectmemory.dll error
Everything looks fine in dns. The only issue I see is with group policy. It does not see the domain controller for the forest.
