You cannot. All the server knows is the specific user credentials it is authenticating. That said you can authenticate those credentials in such a way so that knowing the signed on user you would also know who they are in any environment that uses the same authentication source - and if that source supplies their Windows identity you are golden. The specific setups involved here are outside my experience, though. David J.
