*SIGH*
Yup.. Well I tried setting the switch manually to: 100Mbps/Half/Enabled
(BackPressure) (It won't let me select no Flow control) ifconfiging to
100BT/X it says media: 100baseTX status: active
Same problem. Yes the switch is a Intel 460T. However the other servers are on
the same switch with the same nic card and don't seem to have the problem.
Now.. I have the server set to 100Mb/Full duplex. But same problem :(
Switch: 100Mbps/Full/Enabled (IEEE 802.3x)
Server: media: 100baseTX <full-duplex> status: active
