The NT File Replication Service (NtFrs) was throwing up errors on a Small Business Server 2003 R2 box. There's only one server in that organisation, so no additional domain controllers to worry about.
Typically every morning there was an Event ID 13552 for source NtFrs:
The File Replication Service is unable to add this computer to the following replica set: "DOMAIN SYSTEM VOLUME (SYSVOL SHARE)"
Followed by Event ID 13555
The File Replication Service is in an error state. Files will not replicate to or from one or all of the replica sets on this computer until the following recovery steps are performed
Restarting the File Replication Service or rebooting the server wouldn't clear the errors. The following steps did clear the problem.
- Stop these services: Net Logon and File Replication Service
- Take a backup copy of the C:\WINDOWS\NTFRS\JET directory
- Delete all the files and directories out of that JET directory
- Restart Net Logon and File Replication Service
If you look in the Event Log you should see entries reporting the NtFrs service has started ok AND no more 13552 and 13555 errors :-)
