I'm running four hyper-v servers hosting about 20 virtual servers and I'm using replication.
Currently, my exchange server is in a critical replication state and the report is that it has not replicated since December 6, 2017!!!
When I right click and resume replication, I get a message that a resent is needed, but when I try that, the merge starts and then goes back to error state. I DO see a message that reads Last successful replication for virtual machine Exchange has been delayed. Delay has exceeded the defined critical limit. Replication might be encountering problems.
What I have done in the past is remove replication and then re-enable it. I'm tired of that lazy approach but I'm not sure how to go about troubleshooting replication issues in Hyper-V.
Can someone give me a few basic steps to troubleshoot this?
