Ihave been having problems with vista sp2 and windows small business server 2003 (latest updates), the network was working fine for the past 2 years with both XP and vista and now for last couple of weeksthe vista computer are hanging the network and then freezing when i access files on the shared drive, which then affects all the computers, the only way to fix it is to restart the server. i reinstalled vista twice and replaced the mother board which has the network card intergrated but is still has the same problem
