hey guys, guess what, my AC freezes again yesterday around noon time. :-( I have to reboot the MAIN computer again. Sigh!!! Ummm, so now I don't have any Vista machine on my network and I already replaced the switch. My only guess is maybe my MAIN computer now. But then it's a brand new machine which I purchased in December 07. One other possibility that I can think of is the built in network card. My next step is to disable the on board network card and install an internal network card (PCI). What you guys think? thanks so much, everyone.
