DC Removal Question

[thebeaniemonster]

I have a question about removing a domain controller for a site that no longer exists. The server is a global catalogue server for a remote site.

The site in question was a remote site that was shutdown and the domain controller was sent back to me. If the site was still up (or I was warned before hand) I would of run DCPROMO and removed it properly.

If I try and plug it in at my current site it won't work as it's on the wrong IP range. Now I could change it's IP address and then remove it but I'm not sure if that's the right thing to do? Any help would be greatly appreciated.

Many thanks

How long has it been disconnected from the network for?

It's probably been disconnected for around a month now.

You've probably not exceeded the tombstone lifetime then so you could power it up, change the IP address, reboot and leave it alone for a while to re-sync and then dcpromo it down to a member server
Personally I would just treat it as a failed DC and remove it via ntdsutil;

Did the server hold any FSMO roles? If so you'll need to either transfer or seize the roles to another DC.

I'd bring it online, change the IP, reboot, let it sync. Then I'd remove the GC role, let that take effect, then DCPromo it & reboot. Then remove it from AD.

The problem with using ntdsutil is it can be messy, and then you also need to verify things like DNS, etc.

But either way would work.
