Hey Bert and Al, thanks for your advice. here's a detail picture for my LAN. One MAIN PC with XP PRO-SP2, 4 PCs with XP PRO-SP2 and 1 PC with Vista. I also have one network printer. They are all wired to TWO 100/1000 8-port Dlink switches and they are daisy-chained. (I ran out of ports on the first switch so I need to buy the second switch). Now, I don't know having the two switches daisy chained will be the cause for the freeze problem so yesterday I replaced the two Dlink switches with ONE 16-port Linksys workgroup switch. I am keeping my fingers crossed here. ;-D
Oh, an additional weird thing that I forgot to mention regarding the freeze. I also dedicate the MAIN computer for file sharing besides AC database. And every time when AC freezes on the workstations, I will also lost connection to the shared resourses on the MAIN PC. Isnt that weird? Oh, there is no one using the MAIN PC at all. I set it aside and no one is allowed to use it.
Thanks AL for pointing out the Linksys Hubs issue. That's good to know. And also about the MS application runing on different OSs platform. I would never thought about that. Maybe my next step is to down grade my Vista PC to XP PRO just rule out that possibility. Ummm....
Thanks guys
