Check that the IP addresses and such work?
The NT4 server while interesting is going to find you without support. Is this company going to run long if that server takes a hit from that unpatched exploit?
Just recently about 12 of my users out of 85 have been having problems logging on to the network. They are given a winlogon error and are made to log in as a default user which of course changes their desktop, data, Outlook etc. I have scanned and rescanned the machines but am not coming up with trojans or viruses. What could be creating the problem. Our PDC is an NT4 machine and so is out BDC. We are going to update those machines soon.
