I have been running sbs2003 server without to many isues for a while, today I lost communication, I can't access the network drive, I can't ping the server. I'm able to ping other devices on the network. I removed all the patches that were installed today, 979909, 983583, 976765, 980773, 963090, 976769v2. Then rebooted, no effect. Does anyone have any ideas on what would just inturupr communications?
