VREDIR

When I start up my computer I receive a VREDIR windows
protection error just before login, saying I have to
reboot. This error doesn't occur when I have my other
computer running that is networked together. I suspected
it was my cd-rewriter sw, so I uninstalled it. Now the
problem is still there but I only need to have the cable
connected to my other computer and it will boot up fine.
Has anyone else seen this problem and is there a
solution.
Thank you for your help.
Mike
