Replication fails or Files not synchronized received on file CBMConfig.xml.gzip (4298739)

Replication fails or Files not synchronized received on file CBMConfig.xml.gzip

When replicating files to target Domain Controllers an error is received in Replication Logs

"Cannot access the file because it is being used by another process".

Also, trying to manually copy the file opens an User Access Control (UAC) window.

This behavior is usually related to a workstation blocking the CBMConfig.xml.gzip file in one of the domain controllers, because of that the File Replication Service cannot copy the file.

To find the blocked file, open the Computer Management Application in one of the affected domain controllers and open Computer Management > Shared Folders > Open files, search for opened files in files from C:\Windows\SYSVOL\sysvol\domain name\Policies\Desktop Authority\Device Policy Master folder, notice the computer that blocked the file and see if it is out of disk space which is the usual reason for this behavior.

Then please select all opened CBMConfig.xml.gzip files and then right-click and select "Close open file".

When it is done, replicate changed files again and see if File Replication Service is able to copy the file to the other domain controllers.

This process can also be done manually, open a file explorer in one of the affected domain controllers and open the location for one domain controller which successfully synchronized the files (green status) and browse to \\synchronized DC Name\Sysvol\domain name\Policies\Desktop Authority\Device Policy Master\ and copy the CBMConfig.xml.gzip file to C:\Windows\SYSVOL\Sysvol\domain name\Policies\Desktop Authority\Device Policy Master\ folder.

It will overwrite the blocked file and the replication will be able to copy the files in the future.

However, selecting a random domain controller won't ensure it will be the culprit, this process might need to be done in several domain controllers before finding the faulty one.
