>Cool. Is there a way to determine what domain my computer is in? I'm writing a web app, and I can get the computer name from the system variables on the web server, but I don't know how to get the domain.

Maybe not the fastest, but the easiest way IMO is:

oNet = CREATEOBJECT("WScript.NetWork")
lcDomainName = oNet.UserDomain
