Active Directory Replication Issue


Active directory replication is one of the critical component of Active directory management. Group Policies synchronization heavily relies on the Domain Controllers replication.

 

Where clients starts reporting about the failed shares , failed printer mappings, GPO administrators might see the below error when they navigate to the GPO under GPMC.

An error has occurred while collecting data for Printers.

The following errors were encountered:
An unknown error occurred while data was gathered for this extension. Details: Could not find a part of the path ‘<domain>\sysvol\<domain>\Policies\<GUID>\User\Preferences\Printers\Printers.xml’.

 

The above error occurs due to the Domain Controller replication issues. The first troubleshooting step would be to validate the infrastructure and ensure there are no Replication issues.

For more information, you can follow the MOF for Active Directory to perform the Active directory monitoring and maintainence activities . I have reviewed and Authored the MOF which can be found below,
