Thread:Project:Support desk/Webserver Error with version 1.21.2

Hello,

I installed a MediaWiki 1.21.2 running with PHP 5.3.10 (cgi-fcgi) and MySQL 5.1.59-community under OS Windows Server 2003 R2. Most pages are displayed correctly, but some like "Special Pages" can not be displayed. Instead I just get an error message of IIS Webserver:

FastCGI Error The FastCGI Handler was unable to process the request.

Error Details:

The FastCGI process exited unexpectedly Error Number: -2147467259 (0x80004005). Error Description: unknown error

HTTP Error 500 - Server Error. Internet Information Services (IIS)

How can I get more information about this error? This error occours only with mediwiki versions of the 1.21-tree, the 1.20-versions are working fine.
