RPC server unavailable for DC demotion

[GrnEyedLdy]

Was wondering if anyone has any insight into the following;

This is a classroom setup with only 4 students, so it isn't really represenative of a real organization...

That said,

I have 4 child domains (each containing only one DC). I am removing those child domains from the enterprise by demoting the one and only DC for each domain...3 DC's demote successfully, and the child domains are removed...not a single problem. 1 DC demotion fails with the following error;

The operation failed because:
The directory service failed to replicate off changes made locally.
"The RPC server is unavailable"

I can ping the root server by IP and DNS name resolution.

All machines that demoted successfully and the one that didn't are on the same subnet and all can communicate with each other and the root server in the parent domain successfully.

IP addresses are 192.168.1.1 thru 192.168.1.4 with the root server in the parent domain at the IP of 192.168.1.200

Anyone have any thoughs on this? Am I missing something extremely obvious?

Thanks

Patty
