Symptoms

When you try to install Windows Small Business Server(SBS) 2011 Standard, the installation pauses, and you receive the following warning message:

2691053

Cause

Typically, this message is generated because the Active Directory System Volume (SYSVOL) Replication has not finished.

Resolution

The SYSVOL directory share is used to distribute scripts and files that support Group Policy to client computers on the network. A multi-master replicated copy of the system volume resides on each domain controller. The new server cannot become a true functioning Domain Controller until the SysVol replication finishes.

We recommend that you leave the warning on the screen and that you do not click No in the Warning dialog box. Instead, manually check the SYSVOL replication.

After you verify that replication is working completely, click Yes in the Warning dialog box, and then let SBS Setup retry the operation.

After the Sysvol replication finishes, the Netlogon and Sysvol folders will be shared, and the new server will be considered to be a valid domain controller.

To manually check the SYSVOL replication, follow these steps:
  1. On the source server, restart the File Replication Service service. To do this, follow these steps.

    Note The SYSVOL directory is being replicated from an existing domain controller to the new SBS. The domain controller is the source server.
    1. Click Start, type services, and then click Services under Programs.
    2. Right-click File Replication Service, and then click Restart.

  2. On the source server, open Event Viewer, and then view the File Replication Service event log. To open Event Viewer, click Start, type event viewer, and then click Event Viewer under Programs.

  3. In the File Replication Service event log, look for Event ID: 13568.

    Note The most common cause of file replication failure is NTFRS Journal Wrap. If the source server experiences a Journal Wrap error, an event log entry that resembles the following will be logged:

    Event Type: Error
    Event Source: NtFrs
    Event Category: None
    Event ID: 13568
    Description:The File Replication Service has detected that the replica set "DOMAIN SYSTEM VOLUME (SYSVOL SHARE)" is in JRNL_WRAP_ERROR.

    If the source server is in Journal Wrap, and the source server is the only functioning Domain Controller, follow these steps to set NTFRS on the source server as authoritative:
  1. On the source server, open Registry Editor. To do this, click Start, type regedit, and then click regedit under Programs.
  2. Expand the following registry subkey:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NtFrs\Parameters\Backup/Restore\Process at Startup

  3. In the right pane, double-click BurFlags.
  4. In the Value Data box, type D4, and then click OK.

  5. Exit Registry Editor.
  6. Open Services, and then restart the File Replication Service service.
  7. Check the File Replication Service event log for new errors.
When the Journal Wrap condition is corrected, an event log entry that resembles the following should be logged:

Event Type: Information
Event Source: NtFrs
Event ID: 13516
Description:
The File Replication Service is no longer preventing the computer SERVER from becoming a domain controller. The system volume has been successfully initialized and the Netlogon service has been notified that the system volume is now ready to be shared as SYSVOL.

After the Journal Wrap error is corrected, click Yes in the warning dialog box, and then let SBS Setup retry the operation.

If you have more than one working Domain Controller in the environment, follow the steps in the following Microsoft Knowledge Base article to resolve the NTFRS errors:
290762 Using the BurFlags registry key to reinitialize File Replication Service replica sets

The second most common cause of NTFRS issues is connectivity or name resolution problems. In this case, the File Replication Service log will show an an Error event that resembles the following:

Event Source: NtFrs
Event ID: 13508
Description: The File Replication Service is having trouble enabling replication from SERVER1 to
SERVER2 for c:\windows\sysvol\domain using the DNS name server1.contoso.local FRS
will keep retrying. Following are some of the reasons you would see this warning.

To troubleshoot this issue, follow these steps:
  1. Click Start, click Run, type cmd in the Open box, and then click OK.
  2. Use the Ping command together with the internal fully qualified domain name (FQDN) of the source server to test the connection. To do this, run the following command:
    Ping<FQDN>
    Note In this command, <FQDN> represents the FQDN of your source server.
  3. Try to map a network drive to the sysvol share of the source server. To do this, run the following command:
    Net use * \\<Source_Server_Name>\sysvol
    Note In this command, <Source_Server_Name> represents the name of your source server.
  4. Check to make sure that no firewall programs on the source server are blocking RPC connectivity from the SBS 2011 Standard server.
  5. Open services.msc on the SBS 2011 server, and restart the File Replication Service service.
  6. Check the File Replication Service event log on the SBS 2011 server to see whether any errors occured.
If the NTFRS service is working correctly, you should receive the following event:
Log Name: File Replication Service
Source: NtFrs
Event ID: 13516
Description:

The File Replication Service is no longer preventing the computer CONTOSOSERVER from becoming a domain controller. The system volume has been successfully initialized and the Netlogon service has been notified that the system volume is now ready to be shared as SYSVOL.
After this event is recorded in the File Replication Service event log, click Yes in the warning message dialog box, and then let SBS Setup retest the replication.

More information

An FQDN is a hierarchical naming format that is used together with Domain Name System (DNS) to denote the location of a computer or resource in the DNS tree hierarchy. You can find more information about FQDNs and about supported naming structures in the publicly available RFC 1035 ("Domain names: implementation and specification").

For more information about the ping command, see the following Microsoft Technet topic:
