Exchange DAG member

I have joined 2012 R2 to a domain and installed Exchange 2013. Is it safe to do NIC teaming after all the changes or NIC teaming would break exchange and domain authentication due to change of MAC address?

NIC teaming is not recommended on Exchange. Part of it is due to the what it handles the DAG failovers. The system, in a multi-DAG environment, would not be aware there is a failure and move the DAG to the unimpaired server. It seems you may just be using one server, so you may be able to do it, but I have never seen any indication that Microsoft supports this configuration. That is probably due to the fact they would prefer a multi-DAG configuration for failover.

Also, NIC teaming is still not supported on a domain controller. There can be issues there as well. I have tried it in a test environment and DCDIAG fails when it is ran.

I did find a reference for server 2008. It is supported in one and only one configuration.

"Active Directory Domain Controllers only support teamed network cards in a “Fail on Fault” configuration and not in a load balanced configuration."

"At this time, Microsoft does not support load balanced network teams on domain controllers due to potential data corruption issues."
