求助：Event ID:10021日誌錯誤的解決方法

 

                                

公司域控，win2K3系統，SP2 pack，裝了DNS,DHCP，殺毒軟件是Mcafee 8.5,如今發現系統日誌出現大量的10021錯誤，天天重複出現，一片觸目驚心，見下圖：

 

 

 

1.基本信息：windows server 2003 Standard Edition,sp2.

 

2.根據事件ID，在Microsoft的官網上找到如下這篇文章，http://www.microsoft.com/technet/support/ee/transform.aspx?ProdName=Windows%20Operating%20System&ProdVer=5.2&EvtID=10021&EvtSrc=DCOM&LCID=1033
根據文章的步驟來作：
To assign permissions

1.Using Regedit, navigate to the following registry value
HKCR\Clsid\clsid value\localserver32
The clsid value is the information displayed in the message.
2.In the right pane, double-click Default. The Edit String dialog box is displayed. Leave this dialog box open.
3.Click Start, and then click Control Panel.
4.Double-click Administrative Tools, and then double-click Component Services.
5.In the Component Services snap-in, expand Computers, expand My Computer, and double-click DCOM Config.
6.In the right pane, locate the program by using its friendly name.
7.Right-click the program name, and then select Properties.
8.On the Security tab, in the Launch and Activation Permissions group box, select Customize, and then click Edit.

Add the user to the permissions list, and give the user the appropriate permissions.

但有如下兩個問題：
1）.以上全部步驟中，第一步在註冊表裏找不到那個鍵值在哪裏？
2）.除了第一步以外，其餘步驟我都作了，以下圖：

但該錯誤仍是天天出現，如今都感受鬱悶死了，請高手指點一下解決這個問題啊......謝了....
