exporting active driectory users

I have a Windows 2000 Server (PDC) I am planning to re-build (we'll call it serverA).  While I'm rebuilding my main server, I have a backup machine with Windows 2000 server loaded on it (we'll call it serverB).  I'd like to make serverB a temporary PDC, and would like to transefer all login information from serverA to serverB so that it while I'm working on serverA users will be able to work as they normally would.  

Is there a way I can do this?  If so, please list the process step by step.

Hello there,

Add ServerB onto the existing Domain as a Domain Controller. You will need to follow a few steps so it can neatly take over everything. Once you've completed those steps you can run DCPromo on ServerA to demote it cleanly prior to rebuilding it.

First of all, make sure you setup the new server completely. Install the DNS Service (which should be just a case of installing it then waiting a while). During installation you should have ServerB set to use DNS on ServerA (in TCP/IP Configuration), this can be reset after it's all setup.

Do you use DHCP? If you want to transfer that over to the new server you can use this KB Article:


Make ServerB a Global Catalog:

Open AD Sites and Services, expand Sites, then (unless you've changed it) Default-First-Site-Name, then Servers, then ServerB and open the Properties for NTDS Settings. Tick the box for Global Catalog.

Transfer the FSMO Roles:


Make sure you transfer those, rather than Seize.

Make sure you alter any settings in your DHCP scope so any network clients get the right DNS server and such.

As above, when you've done all that feel free to do Start, Run and DCPromo on ServerA and demote it before rebuilding.

Does all that make sense?
