Hi,
you could use the following code for the same.

System.Security.Principal.WindowsPrincipal wp = new
System.Security.Principal.WindowsPrincipal
(System.Security.Principal.WindowsIdentity.GetCurr ent());

MessageBox.Show(wp.Identity.Name);

Here the messagebox displays the domain name alongwith the
user logged in(the UseriD). Using the ID, you could
validate the user.
