How to Disable DFSRS collectors from AD health?
To disable the DFSRS collectors:
1) In the AA console navigate to Active Directory Health / Agents
2) Select a DC in the "Manage Domain Controllers Tab"
3) Right click on the DC and go to the menu Settings / Domain Controller...
4) In the General tab, under "General Data Collectors" find the first DFSRS collector, and right click on it and select "Settings..."
5) In the settings uncheck "Enabled"
6) Click "Apply to All" and "Yes" in the confirmation dialogue.
7) Repeat steps 4 - 6 for the other DFSRS collectors. There are 6 in total.
Once this is complete the AD Health agents will no longer communicate with the replication systems on the DCs. If this does not correct the issue, also disable the "Conflict encountered during replication" collector, which is located under "Domain" not "Domain Controller" in step 3
