We've started having a problem with one of our clusters. One of the servers has decided it no longer wants to see the network over the x520 T2 card. The work around seems straight forward - simply disable the adapter and enable the adapter and it begins transmitting packets again. So not ideally practical when the server reboots as we start up with no networking.
The server is a Dell PowerVault NX3000 (2950) in a Windows 2008 R2 Enterprise cluster.
It uses it's Broadcom cards teamed with BACS for accessing the iSCSI SAN and the Intel X520-T2 as an ANS ALB Team to access the LAN. It's the LAN connectivity we lose until we do a disable/enable.
It all began following some windows updates, but oddly the other server in the cluster applied the same updates without this issue.
To try to resolve it I uninstalled using ProWin64 and made sure the adapters were gone from device manager. Then reinstalled. Still the same issue.
Can anyone help?
