Hi Rdgs,

Thanks for your response. I am trying to find indication that there are networking issues, but so far can't confirm that this is the case. Pings between the Primary and Secondary MDM and the tie-breaker continue uninterrupted. What seems to happen is that the service on the Primary MDM starts, opens port 6611 for a little bit and then either stops listening on ports 6611 or the MDM service stops completely.

I did you the Installation Wizard to install.

This morning I have tried turning off the host based firewalls completely even though the rules seemed like they should be correct. This didn't change anything.

Currently my Primary MDM has the MDM service running but is not listening on port 6611 and my Secondary MDM has the MDM service stopped and will not start. When I try to start the MDM service on the Secondary MDM it starts several times and then gives up in the stopped state.

Is there someplace where I can look at logs?

My test boxes are VMware virtual machines, I created a DRS rule that keeps them all on the same physical ESX host and the issues seem to have gone away. I'm not sure why that would be the case, but I guess it doesn't really matter as I wouldn't be doing this in production anyway. Thanks for your help.
