We have a 2008 R2 server that has lost network connectivity. The network adaptors are showing but the network connections wil not come up. If you interogate the interfaces using ipconfig, they system does not display any interfaces.
The event log shows cable in and outs, and the Broadcom Manager shows the layer 2 working, and the cable tests fine. I have rest Winsock but the system will not see the interfaces to make a network connection.
All the hardware tests I have run show no errors.
We have installed a 2nd card, exactly the same issue.
Any thoughts
