Is there any way that I can stop Remote Desktop from locking the host
machine, or perhaps get it to automatically unlock the host after the remote
access?

I'm trying to run automated regression tests (using HP's "QuickTest
Professional") on the host machine, but people around the world need to be
able to remote into the machine and then just close the Remote Desktop window
when they're done.  If they do this, the host has the locked message up on
the screen and GUI tests then fail because the windows aren't able to show on
the screen.

One solution to this is using VNC, but there are security flaws that make
this an unwise choice (according to our Info Security dept).

Another solution is to use "PC Anywhere", but this (according to Symantec)
doesn't work with virtual machines, which is something we're moving towards.

Another solution is to use WebEx's "Access Anywhere", but for the way that
we want to use our connections, this could be an expensive solution.

Another solution is to use a ShareWare product I've found called "Remote
Desktop Control", but I don't know how keen our company would be to use
'unknown shareware'.

Another solution is to use NetMeeting, but it's clunky and requires a
username, password and domain name to be typed each time you connect.

One thought I had was to write something in VBScript that unlocks the host,
since I know what the username and password is, of course, but I can't work
out how to do that, even after a day of researching the web.

So..... any ideas anyone please?!

Thanks,
Graham
