I currently have 2 servers running win2k server (both\nwith sp3 installed) We have a new beefy server we want\nto add to our domain with 2k3 server. I tried running\nthe DCPromo tool, but got errors. Then read up about how\ni have to run the ADprep tool on both DC's to prepare\nthem for a 2k3 server. Is the ADprep utility a difficult\nprocess, or can it be done during the day? Or should it\nbe a weekend job, incase of problems? I've read that\nsome installations are smooth and simple and some are\nnot. Want to make sure i get all possible problems\nresolved before i run the utility. Any tips, suggestions\nwould be greatly appreciated. Thank you.
