Manually remove a domain controller server from AD database.

Hello,

We have a defective Windows 2008 domain controller server which cannot be recovered.  

We need to manually clean up the metadata on all other domain controller servers.

Does anyone have a KB that show how to do it?

IF your existing DCs are 2012 or later, you can just delete it from the domain controller's OU - metadata cleanup is done for you.  MAYBE in 2008 R2 as well, I don't recall when they added that feature.  You can still manually clean it up.  Just google "delete failed DC" - I usually use Dan Petri's articles as my checklist.

Make sure to check NTDS objects in site and services, and DNS nameserver ebtries.

Thanks.  It looks like the cleanup is easier in Windows 2008 R2 by just removing the defective DC in ADUC>domain controller OU and in site and services, right?

Even though metadata cleanup is automated, it does tend to leave the DC listed in Sites and Services and the DNS entries.
