About IIS6 (suitable for IIS7) solutions

Describe:

IIS6 application pool is automatically disabled problem Service Unavailable application pool ' DefaultAppPool ' is automatically disabled because of a series of errors in the process of servicing the application pool. Application-specific permission settings do not have COM server applications (CLSID ...).

1. First, open IIS Manager. Check the application pool, and sure enough, "DefaultAppPool" went wrong. And not the usual stop icon.

2. Try to focus on the "DefaultAppPool" application pool, a browsing page will be closed immediately.

4. Will it be the default program pool problem? So, try creating a new pool of programs. Change the default Web site's program pool to new. But the problem remains. A similar log appears.

{a9e69610-b80d-11d0-b9b9-00a0c922e750}
The user NT authority/network SERVICE SID (s-1-5-20) is granted the local activation permission. You can use the Component Services Administration tool to modify this security permission.

For more information, see the Help and Support Center in http://go.microsoft.com/fwlink/events.asp.

6. It's a bit of a play. See the CLSID for {a9e69610-b80d-11d0-b9b9-00a0c922e750} is what service first. Finally, find it in the following registry key:

HKEY_CLASSES_ROOT/APPID/{A9E69610-B80D-11D0-B9B9-00A0C922E750}

7. The name happens to be "IIS Admin Service"

8. Well, find out what it is. To open Component Services from Administrative Tools, locate the IIS Admin service to compare the CLSID to the same

9. After confirming this, the next step is to increase the network service privileges for it.
A start and activate permissions, click "Custom".

B. Add "Network SERVICE" to the list of users,

C. and give local start and activate permissions, save exit.

In addition, if there is a problem, the "IIS wamreg admin SERVICE" To do so, the right to select "Properties", find "security", in the "Start and Activate permissions," edit "Custom", add account
Network Service Network Service to start and activate the local permissions separately.

February 18, 2014 added: Today, a netizen to the small series of feedback his solution, is the Windows Server 2008 R2 64-bit under the use of the php5.5.x version, without the above settings, also resolved the problem.

To solve this problem.

Also have friends mentioned that the options can not be edited, for Gray, what should do?

This is the security feature of win2008 R2 x64. Some core system components can only allow local accounts, TrustedInstaller have full control, not the local Administrators group
To modify the IIS Admin Service on Windows Server 2008 R2, you need to grant registry permissions to the local Administrators group:
1. AppID of IIS in Component Manager
2. Use Regedit to locate the ID that hkey_classes_root\appid\{just found} "
3. Right click on {just found ID}, select permissions
4. In the Permission Settings window, select the owner tag, select administrators for owner
5. Grant administrators a read/write ownership note: Be sure not to modify TrustedInstaller permissions
Now, to run the Component Manager again, you can modify the permissions
