Is there any issues on using vista premium(64 bit) and xp pro on same network?
It will be a Vista premium system as the server/admin and 3 xp pro systems as work stations. Tech support states that this will not be a problem.

I just set up my new system that way, 1 Vista and 1 XP . However, there maybe "share" problems. You might have to go thru the trouble of making sure all files needed are share enabled.

Pro series definitely has problems with any 64 bit configeration

Once again there is a problem with the 64 bit configeration BuT Pro Series is supposed to have this worked out for 2009
