DC File Replication Service日志中出现ID13568错误|活动目录域控制器13568。公司的活动目录域控制器DC上近来会出现Event ID为13568的错误信息，如下：
Event Type: Error
Event Source: NtFrs
Event Category: None
Event ID: 13568
Date: 2007/9/5
Time: 上午 09:00:25
User: N/A
Computer: DC
Description:The File Replication Service has detected that the replica set "DOMAIN
SYSTEM VOLUME (SYSVOL SHARE)" is in JRNL_WRAP_ERROR.  
 Replica set name is    : "DOMAIN SYSTEM VOLUME (SYSVOL SHARE)"
 Replica root path is   : "c:\windows\sysvol\domain"
 Replica root volume is : "\\.\C:"
 A Replica set hits JRNL_WRAP_ERROR when the record that it is trying to
read from the NTFS USN journal is not found.  This can occur because of one
of the following reasons.  
 [1] Volume "\\.\C:" has been formatted.
 [2] The NTFS USN journal on volume "\\.\C:" has been deleted.
 [3] The NTFS USN journal on volume "\\.\C:" has been truncated. Chkdsk can truncate the journal if it finds corrupt entries at the end of the journal.
 [4] File Replication Service was not running on this computer for a long time.
 [5] File Replication Service could not keep up with the rate of Disk IO activity on "\\.\C:".
 Setting the "Enable Journal Wrap Automatic Restore" registry parameter to 1 will cause the following recovery steps to be taken to automatically recover from this error state.
 [1] At the first poll, which will occur in 5 minutes, this computer will be deleted from the replica set. If you do not want to wait 5 minutes, then run "net stop ntfrs" followed by "net start ntfrs" to restart the File Replication Service.
 [2] At the poll following the deletion this computer will be re-added to the replica set. The re-addition will trigger a full tree sync for the replica set.  
WARNING: During the recovery process data in the replica tree may be unavailable. You should reset the registry parameter described above to 0 to prevent automatic recovery from making the data unexpectedly unavailable if this error condition occurs again.  
To change this registry parameter, run regedit.  
Click on Start, Run and type regedit.  
Expand HKEY_LOCAL_MACHINE.
Click down the key path:
   "System\CurrentControlSet\Services\NtFrs\Parameters"
Double click on the value name
   "Enable Journal Wrap Automatic Restore"
and update the value.  
If the value name is not present you may add it with the New->DWORD Value function under the Edit Menu item. Type the value name exactly as shown above.

根据您提供的信息分析，这是由于FRS 服务关闭，从而造成 journal wrap 错误。请根据以下步骤进行排错：
1. 暂时停止DC上的File Replication Service服务。
2. 打开注册表编辑器，导航到以下子项：HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NtFrs\Parameters\Cumulative Replica Sets\ GUID。
3. 将BurFlags的数值数据设置为d2。
4. 重启File Replication Service服务。
