Connected Users? Guru Help....

Hi there guys, I have a problem and am looking for a Guru to help me sort it out.

At the moment i am using Windows NT4, is it possible to list all the other users that are online.

I have seen this done before in a First Class (email software) where it lists all the other users, it also displays information about the user.

I have been looking through different items in VB-WORLD but havent found anything like this.

If you have any ideas then could you let me know
