Since TS was introduced in NT4, the CLIENTNAME variable would give the user's workstation hostname. Great.

Unfortunately, if the user disconnects from their session and reconnects from a different machine, the CLIENTNAME variable would not be updated.

This is a pain for applications which use CLIENTNAME for licensing, or for mapping a certain property from a database.

Since 2005 there has been a workaround - use ReconnAct from LoginConsultants. Definitely a cool tool, this adds two variables, CURRENT_IP and CURRENT_CLIENTNAME which *are* updated after disc/rec.

However, now there's a fix. In Windows 2003 you can apply a hotfix from microsoft which corrects this issue- it also reflects the CLIENTNAME of the session logged in at the console as 'Console' instead of the client workstation hostname. All cool.

It's a private one, so you have to ring up - but never mind, you'll have it on email in five minutes.
