Problemas na replicação entre controladores de domínio.

Se um de seus controladores de dominio parar de replicar os arquivos do SYSVOL e você receber a mensagem abaixo no log do windows, mais precisamente na pasta "File Replication Service":

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.

Siga os procedimentos abaixo para resolver:
1. Pare o serviço FRS. (net stop ntfrs)
2. Abra o editor de registros do windows (regedit).
3. Localize a seguinte chave de registro:
   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NtFrs\Parameters
4. Clique em Add Value,e entre com os dados abaixo :
   Value name: Enable Journal Wrap Automatic Restore
   Data type: REG_DWORD
   Radix: Hexadecimal
   Value data: 1 (Default 0)
5. Saia do editor de registros.
6. Reinicie o serviço FRS.( net start ntfrs)

Se olhar novamente o log de FRS do windows verá uma entrada com a informação abaixo:

The File Replication Service is deleting this computer from the replica set "DOMAIN SYSTEM VOLUME (SYSVOL SHARE)" as an attempt to recover from the error state,
 Error status = FrsErrorSuccess
 At the next poll, which will occur in 5 minutes, this computer will be re-added to the replica set. The re-addition will trigger a full tree sync for the replica set.

Aguarde 5 minutos e o serviço será restabelecido. Demorará uns 2 a 3 minutos para todos os arquivos serem replicados novamente, dependendo do tamanho da pasta.
Quando estiver normalizado, volta à chave de registro, criada num passo anterior, e atribua o valor "0", não sendo necessário reiniciar o serviço dessa vez.
