IIS Issues Windows Server 08

Running IIS7 as a role on win server 2008

Every once in a while intermittently I get this error. I read the KB article at nausia, checked all permission, there is nothing wrong with permissions on the intepub directories. I know Apache is more stable with PHP but I really prefer IIS for a number of reasons. I checked the PHP configurations and there is nothing wrong there. I know that all of the appropriate PHP FastCGI modules and isapi filters are running

Recently I also installed IIS6 as feature because I needed SMTP installed. Wonder if that is causing issues. 

The only script I am running on the server is a PHP script that connects to an IMAP server and retrieves messages and parses the messages for certain information. It has to be done this way, and through PHP and not another email program for a number of reasons. This PHP script auto refreshes every second continuously while the script is running.

Problem is that every so often IIS seams to crash with a 500.0 error for some inexplicable reason. When this happens the functionality of the script ceases and business is lost. If I reload the page manually when this error occurs then the script starts running again with no problems until it crashes again.

Any thoughts on how to prevent this and or cause it to auto refresh the page if an IIS error occurs?

</div> </fieldset></div> <div><fieldset><legend>Most likely causes:</legend>

• IIS received the request; however, an internal error occurred during the processing of the request. The root cause of this error depends on which module handles the request and what was happening in the worker process when this error occurred.
• IIS was not able to access the web.config file for the Web site or application. This can occur if the NTFS permissions are set incorrectly.
• IIS was not able to process configuration for the Web site or application.
• The authenticated user does not have permission to use this DLL.
• The request is mapped to a managed handler but the .NET Extensibility Feature is not installed.

</fieldset></div> <div><fieldset><legend>Things you can try:</legend>

• Ensure that the NTFS permissions for the web.config file are correct and allow access to the Web server's machine account.
• Check the event logs to see if any additional information was logged.
• Verify the permissions for the DLL.
• Install the .NET Extensibility feature if the request is mapped to a managed handler.
• Create a tracing rule to track failed requests for this HTTP status code. For more information about creating a tracing rule for failed requests, clickhere.
