DAG IP Address Conflict? VM Snapshot?


Is there any backup activity that is likely to cause an IP conflict on an Exchange 2010 DAG?

This occurred at 0:06 in the morning, shortly after a DPM backup took place. I'm wondering if this could be related.

I don't think a backup activity to will cause any IP conflict in Exchange 2010 DAG. However still cross-check the NIC Card adapter IP address assisgned on Exchange Server. ALso check the MAPI/Relication network created under DAG is unique they shouldn't be conflicting with each other.

They are unique. This was just an anomaly that occurred at 0:03 in the morning so is quite odd! But if there's very little I can do other than check for any conflicts, then I assume I've covered all bases :-)

Check the same on other nodes which are added in the DAG just to be on the safe side. However backup activity doesn't causes IP conflict unless the IP configured on exchange server is added in other system, If the other nodes added in the DAG IP are also unique then there is nothing wrong in exchange side
