Hi,

We have 3 Exchange 2019 CU12, and we deployed the DAG cluster.

Databases in DAG successfully replicate with all members in the cluster, and "BAD COPY COUNT" is 0 for all databases

our problem is on one of the servers, in this server "Microsoft Exchange DAG Management service" service cannot be started!

after I tried to start this service, I received the below error and generated a "System Event" error with event ID 7031

The Microsoft Exchange DAG Management service terminated unexpectedly. It has done this 1 time(s). The following corrective action will be taken in 5000 milliseconds: Restart the service.

This issue only is on one of the Exchange Servers, I would be grateful if anyone could help me

    guys,

    I found the "Microsoft Exchange DAG Management" service started automatically, without me changing any config on Exchange Server or Windows Server,

    the service was up for 24 hours. but, after rebooting the windows server, unfortunately, the service goes to stop and can't start!

    is it exist a log file for this service? or how can we monitor this service exclusively what happened?
