Server 2012 sysvol has many extra folders.

A client site has two server 2012 DC which has sysvol replication problem using FRS.

dcdiag - all passed
net share netlogon and sysvol - normal
can ping each other using FQDN - normal


When test to place a file "abc.txt" on DC1\netlogon, "abc.txt" wasn't copied to DC2\netlogon.

Then tried the following steps.
1. net stop ntfrs (on two DC)
2. Change the Burflags registry key from 0 to D4
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NtFrs\Parameters\Backup/Restore\Process at Startup
3. net start ntfrs (on two DC)
4. An event 13565 is logged to signal that a nonauthoritative restore is started.

dcdiag - both DC server will have the following results
Starting test: FrsEvent
There are warning or error events within the last 24 hours after the
SYSVOL has been shared. Failing SYSVOL replication problems may cause
Group Policy problems.


Ever restart server but still not help.

Then repeat above steps and find that there are a lot of folders in sysvol.

The replication is solved suddenly now. Can we delete "Polices_NTFRS...." files directly in picture safely? Please help.

Safer method may be to move roles off, demote server, do cleanup, reboot, promo the problematic one again.
