DC and GC

[vpont]

Hello,

Are there any problems if I had to reinstall a Win 2k
Domain Controller, in a different site, that is a Global
Catalog only? The DC does not hold any of the FSMO
roles. The DC with all the FSMO roles is at my site
locally. Will any strange things happen? What will
happen with the DC that was deleted in the Container
Domain Controllers? Will the deleted DC be purged from
the list in time and ADS know it should not attempt
communicate with the deleted DC any longer? Thank you.

If you demote it with dcpromo you should be ok. If you choose to reinstall
it with the same name you should wait until replication has replicated the
changes before you reinstall it.

There are only two ways to remove a domain controller from Active
Directory. The first and prefered way is to demote the DC using
dcpromo. This cleans up not only Active Directory but the registry
of the local machine.

Should for some reason this not be possible you will need to take the
old DC offline and perform a Metadata Cleanup on a good functioning
domain controller to clean up Active Directory. The following
article walks you through the steps necessary to do this including
del;eting the machine account from Active Directory.

To clean up the old domain controller you need to run "dcpromo
/forceremoval" if it has Service Pack 4 on it,

You will also need to remove the server object from AD Sites &
Services and also remove any replication links other domain
controllers may have to it.
