RPC Server unavailable for DC demotion 2

[GrnEyedLdy]

If you saw this post in the NT forum, I apologize, I posted it in the wrong forum...

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

Have you checked your log files for errors? Is RPC started in services as well as RPC Locator? Glen A. Johnson

Glen, both RPC services are started, I tried stopping and restarting the locator service as well. No errors regarding this in log. I believe the problem to be related to the W32time errors I have been receiving lately. Looking to resolve those now. Any other ideas or suggestions will be greatly appreciated!

Thanks for you help,

net time /setsntp:IP_of_Forest_root_DC
run the command on your child domain and it should sync with the main DC. you can also use the fqdn in place of the IP.

FutureTech204 - THANKS!

That was exactly the problem. Demotion completed without a hitch! You just saved me a whole lot of time and aggrevation. Prior to your post I was running the Net Time /setsntp:Ip_of_Forest_root_DC on the forest root DC itself...and the Net Time \\servername /set on the client. Thanks again for clearing that up

Glen,

You are sooooo right! I was so overcome with happiness to resolve this problem so quickly that I completely forgot! I will now give 'props' where they are due. FutureTech204's post was right on the money!

Way to go, that's what it's all about. If somebody comes up with a good solution, let people know it.
