How to find the users in the server?

I want to find out the list of users in the server. My purpose is i want to give certain permissions to certain users and also not to allow other users to use my application.

Using winsock control i can know the user name in the local system, i want to find the list of users in the server if possible.

If any other alternative pls tell me. You can mail me at [email protected]

Thanking you

It looks to be "NetUserEnum". I don't have VB code, though.

i want to find the list of users and if possible their permissions in the server using vb preferably
