We just added a VISTA machine to our network... yea.
Now at login the vista machine flashes an error message that it does
not use automatic updates. I cannot find a way to distinguish between
win XP, NT, 2000, or VISTA. Is there a good way of doing this?

IF OS = "WINNT" THEN
WRITE "Checking Updates for Novell Client for Windows NT/2000/XP."
#\\srv2\sys\public\client\winnt\i386\acu.exe

I tried "and OS_VERSION" but VISTA still tried to run the update. The
only other machines on that part of the network are XP.
