TEAMED NIC and Microsoft NLB resulting in server reboots
Posted on 2013-10-29
I have an 2 Exchange 2013 servers with Client Access Roles installed on Windows 2012. Each server has two physical network connections which I've set-up in a TEAM spreading the load.
In order to balance load them, I installed Microsoft Network Load Balancing on both servers and created a virtual cluster node in multicast mode using the TEAM virtual network connection.
The problem I'm seeing is that every 2-4 hours each servers is rebooting in a sporadic blue screen fashion. Well I imagine a BSOD as the server just times out and by the time I get the server room, i'ts booting up again.
I removed the TEAM and set-up the CAS servers to use a single network connection and when I did that the servers didn't reboot once.
So I'm not sure where to go. The minidump says "Probably caused by : NETIO.SYS ( NETIO+1d532"
I have updated the driver and firmware of the NIC but that hasn't resolved the issue. I presume it's okay to use a TEAMED NIC in an NLB cluster.
Guidance on the cause and resolution would be great.
