One of my two Win 2K sp4 DCs is dying.

November 30, 2010 at 13:02:48
Specs: Windows 2000 SP4, single/2 gb
Win 2K PDC is ok, Win 2K BDC is the one dying. They're configured with DHCP split scope address pool (one gives out 10.1.7.* and one gives out 10.1.6.*). I have 3 other application servers running Server 2003 sp2 online, and two new 2008 servers that are online but have no assigned roles yet. Do I grab one of the 2008 servers to take over for the 2K BDC or will this screw up my existing Active Directory and Exchange 2003 operations?

There is no such thing as a bdc in Active Directory. PDC/BDC are nt4 terms which haven't applied in 10yrs.

You have 2003 and 2008 servers yet are running 2000 AD? Someone hasn't been keeping up!

You can not add 2003 or 2008 unless you upgrade your AD. I would suggest starting with a 2003 upgrade.

To do this you need to run adprep for 2003. Google adprep 2003 for the details.
Once you have upgraded your schema you can now dcpromo the 2003 server to be a DC. I would suggest transferring all of the fsmo roles to it and both should be dns servers as well as global catalog holders.

Sorry for the gaffe on the old PDC/BDC terms. I just was hired here 6 weeks ago, and my first job was to physically clean out the server room of old boxes and furniture so I could actually see the servers I'm supposed to be administering. Nothing had security updates. The two new 2008 servers were in a rack not even turned on! All of the 2003 servers are crammed with healthcare apps (except for the Exchange 2003 server) and I hesitate to make any of them a DC. Do you think I would run into problems if I skip the 2003 upgrade and go straight to 2008? Thanks for the reply and advice!

This should get you started.

I would make sure you have good backups of everything first.

You should also remove the failing DC before it dies so you don't have to do the complicated AD metadata cleanup. You do this by running dcpromo and demoting the controller.
