域内用户组策略设置不一致
 
 
今天发现公司里面很多人的组策略和DC上面设置的不同步，然后就去检查，在dc04上面的日志时候，发现DC的文件复制里面一直报：13568错误，内容如下：
Event Type:         Error
Event Source:      NtFrs
Event Category:   None
Event ID:    13568
Date:          2007-4-20
Time:                   1:05:34
User:          N/A
Computer:  DC04
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"
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.
同时，发现DC01和DC04上面的组策略不一样的，在DC04上面的一个组策略的user version :39(AD),35(SysVol),在DC01上面的都是39，
然后根据错误ID，到微软的网站搜索了一下，这个问题叫：日志折叠错误，根据上面的提示和MS网站上面的解释，应该是域内部的复制出现了问题，导致DC04上面的SysVol文件夹不能更新成最新的，因为GPO都是存在SysVol里面的，所以使用DC04登录的用户的组策略就不是新的，导致域内用户的组策略不一样，问题找到就好解决，
解决办法：
修改了DC04d 注册表的值，
在HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\NtFrs\Parameters 下面，添加：Enable Journal Wrap Automatic Restore ，DWORD值，Value为：1 ，
然后手工启动DC上面的文件复制功能，等了5分钟左右，刷新用户组策略，都是最新的了。
