Symptoms

I log on to the SharePoint Foundation 2010 front-end host as Domain Administrator. When I try to open the Central Administration Web Site, the HTTP error 500 appears.

Failed Request Tracing on Central Administration Web Site shows the following:

===8<===
ModuleName IIS Web Core
Notification 1
HttpStatus 500
HttpReason Internal Server Error
HttpSubStatus 19
ErrorCode 2147942433
ConfigExceptionInfo \\?\C:\inetpub\wwwroot\wss\VirtualDirectories\7980\web.config ( 237) :This configuration section cannot be used at this path. This happens when the section is locked at a parent level. Locking is either by default (overrideModeDefault="Deny"), or set explicitly by a location tag with overrideMode="Deny" or the legacy allowOverride="false".
 
Notification BEGIN_REQUEST
ErrorCode The process cannot access the file because another process has locked a portion of the file. (0x80070021
===8<===

Cause

Section management is not delegated for the Modules, Handler Mappings, and HTTP Response Headers sections.

Resolution

For POA 5.5 and later, use the following automated procedure:

1.   Log on to the SharePoint Foundation 2010 front-end host as Domain Administrator.
2.   Go to the PLESK_ROOT directory, e.g. C:\Program Files (x86)\SWsoft\PEM\.
3.   Run the SharePointFixDelegation.ps1 script. This script will fix the problem for all broken SharePoint sites.

- OR -

Use the following manual procedure:

1.   Log on to the SharePoint Foundation 2010 front-end host as Domain Administrator.
2.   Open Internet Information Services (IIS) Manager.
3.   In the navigation tree, select the webserver.
4.   Click on the Feature Delegation icon.
5.   In the Actions area, click Custom Site Delegation.
6.   In the Custom Site Delegation area, select the SharePoint Central Administration v4 Web Site.
7.   In the list of features, select the Modules feature.
8.   In the Actions area, click Read/Write.
9.   In the list of features, select the Handler Mappings feature.

11. In the list of features, select the HTTP Response Headers feature.
