Lỗi DCOM trong Windows 2003 ?

Server của mình báo lỗi thế này:

DCOM got error "The dependency service or group failed to start." attempting to start the service winmgmt with arguments "" in order to run the server: {8BC3F05E-D86B-11D0-A075-00C04FB68820}

Mình có search cách giải quyết thì có recommend này:

In my case, I had the same CLSID as Linda. Here is the additional information she omitted that is needed to correct the problem: In Component Manager, under DCOM config, go to netman, browse to the Security Tab, edit the Launch and Activation Permissions and make the necessary changes. In this case, NETWORK SERVICE needs to be added with Local Launch and Local Activation permissions.

Mình mới search tiếp CLSID là gì:
What is a CLSID?
A Class ID (CLSID) is a 128 bit (large) number that represents a unique id for a software application or application component. Typically they are displayed like this "{AE7AB96B-FF5E-4dce-801E-14DF2C4CD681}".

You can think of a CLSID as a "social security number" for a piece of software, or a software component.

What are they used for?
CLSIDs are used by Windows to identify software components without having to know their "name". They can also be used by software applications to identify a computer, file or other item.

Trong dòng này có hướng dẫn cách khắc phục nhưng mình ko tìm được chỗ để sửa:
