How to disable AD Client Monitoring Discovery

For some reason the relationship between these agents and the dcs are not being removed.

We can try to run the command to remove them manually.

Please perform the following steps.

1) Disable the “AD client Monitoring Discovery”  discovery for one of the agent servers that still show a demoted DC in GC search time.

    Active Directory Client Perspective

2)In Opsmgr powershell run  “Remove-SCOMDisabledClassInstance”

If this doesn’t resolve the issue I’ll contact the product team again.

Please let me know how it goes.
