cluster failover
I have an Exchange cluster that likes to switch over ever other day. It does not matter on time of day or time of week. It all starts with a 1135 Event ID and then is followed by 1562 and 1069 and 1564 and 1177.
We have servers in two different states.
The event ID says the cluster service may have stopped or lost communication with other active nodes. I've added to the nic team for communication.
The log on the near server says the far server has lost communication and the log on the far server says the near server has lost communication at the same time.
The switch is not reporting any problems. I'm not getting any reported problems with the nics either.
We've recently upped the samesubnetdelay and crosssubnetdelay.
There was one new program installed but that has since been uninstalled.
The only other things that have happened since the time when all is well to now is just windows updates.
Any help would be greatly appreciated. Thank you

Could you check Cluster.log logfile and paste entries when cluster switch over?
