From the event logs, we found the following error events that indicate corrupted WMI service.

Performance Module could not find a performance counter

事件類型:        警告
事件來源:        WinMgmt
事件類別目錄:  無
事件識別碼:     60
描述:
WMI ADAP was unable to process the performance libraries: 0x80041001

事件類型:        警告
事件來源:        Health Service Modules
事件類別目錄:  無
事件識別碼:     10102
描述:
In PerfDataSource, could not resolve counter Web Service, Current Connections, _Total. Module will not be unloaded.

Solution
=======
To rebuild all Performance counters including extensible and third party counters in Windows Server 2003, type the following commands at a command prompt.
Press ENTER after each command.

cd \windows\system32
lodctr /R

Note /R is uppercase.

Windows Server 2003 rebuilds all the counters because it reads all the .ini files in the C:\Windows\inf\009 folder for the English operating system.

如果執行後問題依然存在，請您使用修復 WMI repository 的方法嘗試將問題解決。
1. Disable the WMI service:
    NET STOP WINMGMT
2. Reboot Server
3. Backup the WMI repository:
    - Copy the folder "%windir%\system32\wbem\Repository" to a different folder.
    - Rename the folder "%windir%\system32\wbem\Repository" to "Repository000"
4. Enable the WMI service:
    NET START WINMGMT
5. Reboot Server
6. Monitor the server and check if the problem is fixed.  If not, run the following batch commands to repair WMI:
    @echo off
    sc config winmgmt start= disabled
    net stop winmgmt /y
    %systemdrive%
    cd %windir%\system32\wbem
    for /f %%s in ('dir /b *.dll') do regsvr32 /s %%s
    wmiprvse /regserver
    winmgmt /regserver
    winmgmt /clearadap
    winmgmt /resyncperf
    net start winmgmt

7. Monitor the server and check if the problem is fixed.  If not, run the following command to reinstall WMI:
    rundll32 C:\windows\system32\Wbem\wbemupgd.dll, RepairWMISetup

[Symptom] Can I change the default listening port of Remote Assistance ?

[Explanation] The answer is no, this is by design behavior.

· Remote Assistance uses the DCOM port (135) only to allow DCOM communication for remote launching of RA on the novice side – which in turn opens Remote Assistance listeners on the novice machine.

· These listeners are opened on dynamically chosen ports. In Vista/Win 7 there really is no way to configure this range in any way. What we do suggest is instead of using port based exceptions, add an exception to allow traffic from “msra.exe” from your firewall.

· Remote Assistance is using dynamic ports from the port range starting at 49152 and ending at 65535.

[Suggestion]

· Consult Firewall Vendors, there may have a mechanism to look for those RPC Packets and dynamically open the negotiated port. (as long as the Firewall Device is configured to do so)

[Reference]

The default dynamic port range for TCP/IP has changed in Windows Vista and in Windows Server 2008

3.登入Uers 帳號 測試
另外.如果排程執行為 Batch file , 您亦需要允許 User 可以執行 CMD.exe
cacls  %windir%\system32\cmd.exe /E /G BUILTIN\Users:F

使用FCS或是MOM的系統管理員常常遇到以下幾個狀況：

1.Admin Console裡面的電腦帳號有些可能都已經報廢了，但是Console還有這台電腦。

2.系統都重灌或是電腦名稱都改變了，不斷的新資料和舊資料交雜。

3.Active Directory 使用者及電腦 裡面的資訊和MOM無法同步。

針對以上的問題，我們推出了以下的工具：
