Hi

There is nothing builtin that can help you with that, but there is some ways
that might work for you:

==================================================
You could install the CCONNECT Microsoft Resource Kit utility onto every
computer, it is in the Win2k Server Resource Kit, Supplement 1 (you will need
a SQL server database as well):

>From the CConnect docs:

Features:

 Is completely hidden from the end user.
 Keeps track of all computers that users are logged into.
 Allows concurrent connection limitations to be set on a per-user/group basis.
 All information is kept in a Microsoft SQL Server database assigned by the
Administrator.
 Tracks last known user of the computer
 Monitors what logon server users are logging into.

More here:

http://support.microsoft.com/default.aspx?scid=KB;EN-US;237282

==================================================
If CConnect is not an option, putting PsLoggedOn.exe in the logon script may
work. It is in the free PsTools suite at
http://www.sysinternals.com/ntw2k/freeware/pstools.shtml

>From the docs:
"If you specify a user name instead of a computer, PsLoggedOn searches the
computers in the network neighborhood and tells you if the user is currently
logged on."

==================================================
Here is a third variant:

and then there are 3rd party buy products, here is one example:
