As far as I can tell there is no antivirus software running of any kind.

I can't do this at the moment, as it requires yet more favours from the
people at the other end (who I wouldn't have to bother at all if RealVNC
worked). I'll try this as soon as I can. I wonder why your XP box has a
problem with telnet. If it is the case that some versions of Windows XP
block all ports regardless even when all firewalls and security are turned
off, then we have a real problem. Perhaps I'll have to trash the remote PC
entirely and try to downgrade it to Windows 98 before Real VNC will work?
