Does it hang randomly once you are loged into the server or does it lock up before you can even log-on?
NT 4.0 has problems with certain types of modems, I have noticed that if a modem application fails and causes a system crash the next time NT loads it will lockup- and lockup the only way to fix the problem is to remove the modem card, reboot the machine, login then logout - shutdown and resinstall the modem card it will then work again. It has happened on a couple of the servers at the office and 1 at mine friends office, stange but as yet no real reason behind it.
If it is locking while loged in then the event viewer or stackdump info is your best bet at being able to locate the problem.
