None, and there was a good 30 days between the first 2008 DC and the last 2003 DC.

I started the same way you are going to, demote/remove one and bring it up. It was a non-event, while I like many of the things in 2008 it feels more like a feature pack than an new server OS. The only issue we had were some WINS oddities with our old ghosting boot disks, just needed an lmhosts file on the disk or turn on the master browser service in the DC's.

Currently I have three domain controllers. I'm planning on demoting a DC, removing it from the domain, wiping the box, installing 2008, then run the necessary adpreps... anything else to take into consideration? I can keep the other two domain controllers running 2003 and leave the domain in mixed mode can I not? I also have a 03 member server running 03 exchange if that makes a difference. Any ssuggestions or caveats appreciated. Steve ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
