Woring domain name when Upgrade from WiNT server to windows 2000 server.

I did one stupid error when upgrading my PDC server from WinNT 4.0 server to OS to Windows 2000.
The error that i amke was i provide the wrong domain name when prompt by the system during the upgrade.

Now, my domain name has become svr01.basf-petornas.com.my

svr01 is the server computer name.

The correct domain name shoild be basf.petronas.com.my

What can i do to rectify the error without having to restore from the backup.

Any susgestion.

Hi,

I'm afraid to bring you very bad news. Windows 2000 cannnot rename the domain name, so the only way to gte it changed is to do a reïnstall of the domain. You can however upgrade to Windows 2003 and go into 2003 native mode, the 2003 servers do support renaming the domain name..

I can upgrade to windows 2003 because it is not our standard OS for corporate use. How to re-install the domain ? do you have any procedure for it. During the re-installation, will there be any impact to existing application that using the user id for login. Thank you.

Hi,

I would suggest reïnstalling the domain, this means you would have to break down your old domain and AD, with all it's users and machines in it.. If you don't have a very big domain, you could try and rebuild it. To do so, execute the dcpromo command on all Domain Controllers to break down the domain. Do keep in mind you will need to recreate all users if you do this (and also compu accounts and stuff)...

You could use the link i gave you to rename the 2000 domain, but it will cost ya a lot of time and a spare machine with NT4 SP6a on it...

So, if i have a spare machine to install as BDC ,so i will be able to keep all my user account in the BDC and conenction to the network for user to logon. At the same time, i will disconnected windows 2000 server from my network and perform the domain rename processs as stated in the link.
