I have tried to research existing questions/knowledge base but nothing seems to apply so far.
I have 2 existing W2K3 DCs and need to setup a new W2K8 DC.
I am running adprep from the 2008 disk (32bit) on my main DC (win 2003) which is a schema master.
adprep /forestprep run successfully without any errors but when running 'adprep /domainprep /gpprep' I receive an error:
Adprep was unable to complete because the call back function failed.
Error message: (null)
It seems like AD replication runs OK (log attached) and dcdiag and netdiag do not return any errors.
All log files attached.
