I have been having a reaccuring problem with my windows 2003 small business server. I have tried to install it to 3 seperate systems to nail down the problem but it occures the same way on each computer. about 12 hours after install if i reboot it will then proceed to hang up while loading the admin account. It seems to be hanging up on explorer.exe. I can control alt del and look at list of processes. I can log the account out and relog it only to have it hang at the same spot each time. It appears to not want to load explorer. Any ideas of what it could be.

Hmm, what system are you installing on, is it a home made server or a branded one, if its branded give me make and model number, you can try logging in safe mode, hold f8 as boot time, have you done a full format on the drive before installation?

Make sure it is not hung up by waiting a good 10 or 20 minutes for the login. Your client pc and your server should have the same time and time zone or your logins could be hell! "i woke up this morning and all of my stuff was stolen and replaced with exact duplicates."
