Nameing a Windows server

I plan on rebuilding (reformatting) a server that is currently on my jobs 2003 Windows server domain.  After I un-join it from the domain, could I rebuild the server then rejoin it to the domain with the same computer name?  Is this ok or will it cause problems?  What steps would you recommend?  Would you also recommend deleting the servers entry in Active Directory after it is un-joined or is that unnecessary?

you can do this but reset the computer account in Active Directory before rejoining it to the domain.

I would prefer the safer path - after decommissioning it, delete its entry from AD, then rejoin the domain.. preferably with a new name. Just to be on the safe side.

Unjoin this server from domain, then delete object from ADUC also delete it from DNS server. Once this is done you can rejoin it to domain.

There is no need to delete the Object from ADUC, when you reset the account it severs the connection between the server and the domain and then the computer needs to be re-added anyway. This also has the upside of as soon as you rejoin the computer to the domain it is already in the correct place to apply any GP's that should be ran on it.

Agree w/ CaptainGiblets. All it will do is tell you that there is an existing account for it in AD and ask you if you want to use it.

When you unjoin the computer from the domain the computer account is removed from ADUC.  You will have to purge the DNS record for the unjoined server.  If you use the same name and IP after the rebuild anything that references the server in group policy or UNC name will not need to be changed.  If this server is a domain controller you will want to transfer any FISMO roles that it holds.
