Windows Updata 錯誤代碼 : 0x8007f004解決方法

方法一:
Go to "SecPol.msc > Local Policies > User Rights Assignment"
Make sure the account used for updating have the privileges stated.
The following permissions are required:
1. Back up files and directories
2. Debug programs
3. Restore files and directories
4. Manage auditing and security log
5. Take ownership of files or other objects
Note that other than local security policy, the setting can also be affected
by domain policy.
The problem could be with the Group Policy at the domain level.
On the DC, if "Manage auditing and security log" has permissions for Domain
Administrator only, remove it.

方法三:
另外一例為XpPro也參考看看
I found a bit of a workaround, but honestly not sure what caused the issue in
the first place. This was done on a laptop running WinXP Pro. I manually
downloaded Windows Installer 3.1, booted to safe mode and installed it
successfully while logged in as Administrator. Rebooted and let it come up
normally and all other updates applied successfully.

方法五:
Register the DLL files:
Click Start · Run and type "cmd" without the quotes and press enter. Type in
the following and press return after each line:
REGSVR32 %windir%\system32\wuapi.dll
REGSVR32 %windir%\system32\wuaueng.dll
REGSVR32 %windir%\system32\atl.dll
REGSVR32 %windir%\system32\wucltui.dll
REGSVR32 %windir%\system32\wups.dll
Enter "exit" and press enter.

方法六:
單獨處理Windows Installer(跟方法三一樣)

方法七:
使用WinMerge
比對secpol.msc

方法八:
使用WinMerge
比對regedit

方法九:
比對兩台的%WINDIR% , "Program Files" , "Documents and Settings

===============================================
PS:原則上是在方法一就可以解了,這問題有趣,Windows 2000 Server的網域,所以加入DC的Server都不會有問題
但是DC Server經過中毒或其他人為因素,Member Server就不會再做Windows Update了,以上的方法提供給同好研究.
