I performed a migration from SBS 2003 to SBS 2011. I've got all my users, groups, files, etc. It seemed to go OK, but now when I run a DCDIAG on the 2011 server, I get
Starting test: Advertising
Warning: DsGetDcName returned information for \\OLDSERVER.domain.local., when we were trying to reach NEWSERVER.
SENDER IS NOT RESPONDING or IS NOT CONSIDERED SUITABLE.
I can't demote my OLDSERVER because it tells me no other Active Directory domain controllers for that domain can be contacted.
Any help is greatly appreciated. I'm under a tight time crunch here.
