Here is some code that populates two list controls, one with all users, the
other with all groups, from a named NT domain server:

Dim MyServer As System.DirectoryServices.DirectoryEntry
MyServer = New
System.DirectoryServices.DirectoryEntry("WinNT://<servername>")

MyServer.Children.SchemaFilter.Add("user")

For Each user As System.DirectoryServices.DirectoryEntry In
MyServer.Children
  lstUsers.Items.Add(user.Name)
Next

MyServer.Children.SchemaFilter.Clear()
MyServer.Children.SchemaFilter.Add("group")

For Each group As System.DirectoryServices.DirectoryEntry In
MyServer.Children
  lstGroups.Items.Add(group.Name)
Next

I'm not aware of any way of receiving updates from a non-Active Directory NT
domain when user information changes. If you can use Active Directory there
are a number of mechanisms, but I don't think they are available through the
.NET libraries so you will have to use unmanaged code. Take a look at
