Hello,
I have to point out that this should not be a problem, but somehow I'd never do change the IP address of a DC...

Lets see, you change IP and Subnet Mask and in DNS your server is listed with the old IP Address?
If so, you can simply change the static DNS entries for the Server in DNS and recreate the Reverse-Lookup-Entry. Be sure that you find all entries to that server in the DNS settings and the Subfolders of your Forward lookup Zone.

Then, do an IPconfig /flushdns on all your clients and maybe even an IPconfig /release followed by an IPconfig /renew (you can script a little Batch-File that does all these steps for you...
That should do the trick...

What makes you say this? Can you post an error message?

What instructions did you follow for changing the IP address?

Don't forget you need to update the DNS server settings in your DHCP scopes as well as any other static entries, e.g. on Servers.
