Does anyone know if its possible to obtain the Client Name (that is, the host name) of a user connected to a terminal server remotely (with a script or command line tool)? You can obtain this information graphically from the Terminal Services Manager snap-in (see screenshot).

The Query User command (or QWINSTA) only returns the Session Name.

Alternatively, remotely reading the user's %CLIENTNAME% environment variable would work as well.

Does "query user" give you what you need?

Unfortunately, no.

The closest thing it gives to client name is session name (RDP-TCP#xx), but I need the actual host name that the client is connected from.

You'll probably have to check out the WTS API's on MSDN, then, as that's the only other way I know of getting info from a TS machine.

I've tried using those (WTSManager.dll) in a vbs script, and the script works when run from the terminal server itself. But I can't find a way to get the script to work remotely from another computer.

Looking through the article I noticed it mentions using "WTSOpenServer( LPTSTR pServerName)" to connect to a different server, but I haven't had luck getting it to work yet.
