We have a Dell PowerEdge T300 with Intel Xeon X3323 2.50GHz and 16gig RAM runningWindows Server 2008 FE, SP 1 (SBS 2008) with a Broadcom NetXtreme Gigabit Ethernet.
About once a week, usually when network traffic is high, the network card goes to "not connected" state showing like the cable is missing. Changing cables, switch ports, has no effect the same as doing a "repair" from the network connections. The only way to fix this, is rebooting the server.
Needless to say, it is becoming a big problem with the customer. Any ideas what is the cause of this or what to look for in order to troubleshoot this issue?
The disconnects used to happen at almost the same time every week (during backup to a NAS)
