Restoring missing GPO file due to DFSR-R replication conflict

Question

We are encountering a GPO issue when running gpupdate /force on the workstation. It appears that some xml files of this GPO are missing due to DFSR-R replication conflict. How can these files be restored?

Hi @LULU

If you have already GPO backup it's simpler to use this backup to restore GPO.

It's recommended to backup GPOs to be ready to restore missing file when you encountering this kind of issue.

To restore missing GPO files due to DFSR-R replication conflict, you can use the Get-DfsrPreservedFiles and Restore-DfsrPreservedFiles Windows PowerShell cmdlets. These cmdlets are included with the DFSR module in Windows Server 2012 R2. Alternatively, you can use the RestoreDFSR sample script from the MSDN Code Gallery. However, this script is intended only for disaster recovery and is provided AS-IS, without warranty.

To recover lost files, you can restore the files from the file system folder or shared folder using File History, the Restore previous versions command in File Explorer, or by restoring the files from backup.
