From: Meinolf Weber [MVP-DS] on
Hello Miha,

This may be a way but not a real solution. Please describe more details about
your domain setup and post an unedited dcdiag /v, netdiag and repadmin /showrepl,
so we can check for errors on the DCs.

Was there any crash before this starts or is the server installed from an
image that isn't sysprepped?

Best regards

Meinolf Weber

If this had not solved your issue, sounds like this could also be cause by
some networking (offload) issues. Broadcom NICs ?

Hi
Funny, I see so many possible solutions... What about starting with the
basics?
Communication problems? Start your network sniffer...!!!

I hope that the information above helps you.
