TabMon service failed to start with multiple hosts

Hi there

I added two clusters as below in my TabMon.config file.

But after the above change, I am unable to start TabMon service. Excerpt of log file indicating the error is provided below.

Any help would be greatly appreciated.

Thanks

There are 2 things that I can think of that would cause this.

1. The remote registry service is not enabled on one of the hosts.
2. The two hosts in the clusters are not in the same subnet.

To verify these options please go on both hosts and check that the Remote Registry service is enabled and gather the IP addresses. Once done, please send the information.

Thanks, Dan

Sounds great. Thank you.
