I seem to be having a slight problem on our network with our XP workstations. It appears that for whatever reason the NIC card on some of the workstations seem to be disabling and the reenabling itself. The event viewer shows that the nic is going up and down more than 10 times per minute. It isnt happening on all workstations. XP is latest service pack. When I check the switch logs it shows the port also toggling back and forth.
XP event viewer also shows "detected spanning tree on network" right before the nic goes down.
I dont have any strange config on the ports. They are all associated with the appropriate VLAN.
Any ideas ? Anyone seen this before ?
