公司域控，win2K3系统，SP2 pack，装了DNS,DHCP，杀毒软件是Mcafee 8.5,现在发现系统日志出现大量的10021错误，每天重复出现，一片触目惊心，见下图：
1.基本信息：windows server 2003 Standard Edition,sp2.
2.根据事件ID，在Microsoft的官网上找到以下这篇文章，http://www.microsoft.com/technet/support/ee/transform.aspx?ProdName=Windows%20Operating%20System&ProdVer=5.2&EvtID=10021&EvtSrc=DCOM&LCID=1033
根据文章的步骤来做：
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.
但有以下两个问题：
1）.以上所有步骤中，第一步在注册表里找不到那个键值在哪里？
2）.除了第一步之外，其他步骤我都做了，如下图：
但该错误还是每天出现，现在都感觉郁闷死了，请高手指点一下解决这个问题啊......谢了....[/img]..
