IIS6 application pool is automatically disabled problem application pool 'defaultapppool 'is automatically disabled

1. First, open the IIS manager. Check the applicationProgramPool, "defaultapppool" error. And it is not a normal stop icon.

2. Restart the "defaultapppool" application pool and close it immediately after you browse the page.

3. It is time to view the event log. The following types of logs are found:

4. Will it be a problem with the default program pool? So, try to create a new program pool. Change the default website program pool to a new one. But the problem persists. Similar logs appear.

Event Type: None

5. Another log in the event log caught my attention as follows:

Event Type: Error
Event Source: DCOM
Event Type: None
Event ID: 10016
Date:
Event: 16:12:33
User: nt authority \ Network Service
COMPUTER: Mail
Description:
Application-the COM server application (CLSID is

The Local activation permission for grant the user nt authority \ Network Service Sid (S-1-5-20 ). You can use the component service management tool to modify this security permission.

For more information, seeHttp://go.microsoft.com/fwlink/events.aspHelp and Support Center.

 

6. It's a bit playful. Check out what service CLSID is for {A9E69610-B80D-11D0-B9B9-00A0C922E750} First. Finally find it in the following registry key:

Hkey_classes_root \ appid \ {A9E69610-B80D-11D0-B9B9-00A0C922E750}

7. The name is "IIS Admin Service"

 

8. Okay. Find out what it is. Open "component service" from "Administrative Tools", find the IIS Admin Service, and check whether the CLSID is consistent.

 

9. After confirming this, the next step is to add the network service permission for it.
A. Start and activate permissions and click "Custom "..

 

B. Add "Network Service" to the user list ",

 

C. Grant local startup and activation permissions to save and exit.

 

Solve this problem.
