Question : No record of File Replication System, SYSVOL started - DCDIAG Errors

When Running DCDiag on my a newly installed DC I get this error:

Starting test: frssysvol
         Error: No record of File Replication System, SYSVOL started.
         The Active Directory may be prevented from starting.
         ......................... S-DCBKUP-07 passed test frssysvol
      Starting test: kccevent
         An Information Event occured.  EventID: 0x40000456
            Time Generated: 04/04/2007   09:57:49
            (Event String could not be retrieved)
         ......................... S-DCBKUP-07 failed test kccevent
      Starting test: systemlog
         An Error Event occured.  EventID: 0xC0001B70
            Time Generated: 04/04/2007   09:53:44
            (Event String could not be retrieved)
         ......................... S-DCBKUP-07 failed test systemlog

I went into site and services and selected replicate now, waited 1/2 hour and checked, no improvement.

I checked event viewer, there are no entries in the File Replication area and only informational records in the Directory Service area.

When I forced the replication, this event was logged in the application log:
Event Type:      Warning
Event Source:      MRxSmb
Event Category:      None
Event ID:      3019
Date:            4/4/2007
Time:            9:56:01 AM
User:            N/A
Computer:      S-DCBKUP-07
Description:
The redirector failed to determine the connection type.

any help would be greatly appriciated!

Thanks

Answer : No record of File Replication System, SYSVOL started - DCDIAG Errors

Is the SYSVOL folder shared out?
Do you see event 13516 that says "frs is not preventing this DC becomes a DC blah blah..."?

If you don't see either, then run more diagnostic tests such as netdiag. Most of the time the cause lies in your DNS/network.

the simplest way to test if your FRS is working:
add a blank folder under one of the policy folder, see if that new folder being replicated to other DCs. Do it for both directions.

MS provides tools such as frsdiag, ultrasound to check frs health.
