You mean different than User/Server Manager tools?

Not quite sure what you are looking for, but I've used the below DOS prompt code before to capture users into lists (if I recall my syntax right):

showmbrs Domain\Group > C:\yourdestination\anyname.txt

It requires the Resource Kit to be installed, and I haven't used it since we upgraded from NT to Win2K (it's hard to test, my servers are now in a remote secure vault). But, is that what you're looking for?

Either way, it may help someone else to answer your question, if that's not what you want or it doesn't work on Win2K.
