Hi,
Thank you for your question.
According to your description, this warning could be Event 12317. An Event 12317 is caused when the NT AUTHORITY\Authenticated Users group is not a member of the BUILTIN\Users group in the domain.
To resolve this event, add NT AUTHORITY\Authenticated Users to BUILTIN\Users group on the PDC emulator. You can check this by launching Active Directory Users and Computers and looking in the Builtin folder for the domain. The Users group must contain the Authenticated Users group. If it does not, you can add it using the snap-in. Next, stop and restart the FSRM-related services (srmreports and srmsvc) on the file servers where FSRM is running.
You may refer to this article for more details
