Preliminary:
> Make a backup copy of all folders/files under c:\windows\sysvol.
> Make a backup copy of all group policy objects by using the Group Policy Editor.
 
Start RegEdit.
 
Move to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\NTFRS\Parameters
 
Create the following DWORD values:
 
"Ntfs Journal size in MB"  (maximum decimal value = 128)
"Enable Journal Wrap Automatic Restore" (set value = 1)
 
After you create the entries and close RegEdit, restart the NTFRS service.
Note that the folders/files that you copied earlier may now be missing.
 
Restore any missing folders/files.
 
Is the c:\windows\sysvol\sysvol\<domain>\scripts folder still shared as Netlogon?  If not, then search the
Registry for all instances of SysVolReady and change the value from 0 to 1.
Restart the NTFRS service.
 
Go into the Group Policy Editor and click each group policy.  You may receive a
warning about inconsistent permissions.  Click OK to correct the inconsistency.
