RPC Server is Unavailable on a DC

I have 2 DC's in one forest/domain with about 600 clients

Both DC's are running 2003 Enterprise with SP2 and fully patched. I have started doing some DNS troubleshooting per this article as clients hang on "Applying Personal Settings"

https://www.experts-exchange.com/questions/21192026/Applying-personal-settins-takes-long-time.html

On my main DNS/DC Server, when I make the changes and do a ipconfig/registerdns - I get the "Registration of DNS records failed: The RPC server is unavailable". I have rebooted the server to no avail. I fear this could be causing some of the DNS issues I am having. How do I begin troubleshooting this error?

What about the RPC errors I have posted above?

RPC errors are most frequently caused by DNS misconfiguration or other issues within DNS. Use the steps that I outlined in a previous post to troubleshoot your DNS environment, which the RPC errors are likely symptomatic of.

Excellent!! I had never seen anything stating that the DHCP client needs to be running. This post saved me!

Some knucklehead (probably why he was replaced) set the DHCP client to disabled on an SBS 2003 server.

Enabling and starting DHCP client fixed the "RPC server unavailable" error on ipconfig /registerdns.

Thanks!
