Anyone with VMWare experience?

I have a quad core 2.4ghz and 6 gigs of ram which should be overkill to run vmware with vista but guess what? I ran into the same problems as you did. There would be constant lag, client and host could be connect at the same time, etc..

The moment that you downgrade to XP, you'll realize that Vista is the crummiest OS following windows ME.

seriously, downgrade and you'll never look back.
