Thanks for your reply ,
I have checked those settings and they are OK.
I am able to offer remote assistance from a Vista machine to an XP machine,
the problem is when I want to offer remote assistance from a Vista to another
Vista machine. Beside receiving the earlier mentioned error message on the
expert machine I get the following error logged in the event-viewer of the
novice machine ( the machine that I want to offer assistance to). Also note
that I am in a domain environment and that offering an assistance by
entering the machines IP or name ( not by creating an invitation that needs
to be mailed to the users)
