AD domain controller problem

  1. SYSVOL and NETLOGON shares were not online on the DCs
  2. NETDIAG and DCDIAG tests on the DCs both had major failures, primarily inability to locate any DCs, Global Catalog Servers, time servers, or domain names

All of these problems utlimately tied to an error in the File Replication Service log on the DCs:

Event Type: Warning
Event Source: NtFrs
Event Category: None
Event ID: 13566
Date: 6/10/2010
Time: 9:15:56 PM
User: N/A
Computer: OBIWAN
File Replication Service is scanning the data in the system volume. Computer OBIWAN cannot become a domain controller until this process is complete. The system volume will then be shared as SYSVOL.

To check for the SYSVOL share, at the command prompt, type:
net share

When File Replication Service completes the scanning process, the SYSVOL share will appear.

The initialization of the system volume can take some time. The time is dependent on the amount of data in the system volume.

Solution :

There is a registry value called BurFlags located in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NtFrs\Parameters\
Backup/Restore\Process at Startup\
.  The value needs to be set to d4 to allow SYSVOL to be shared out.
