[FastCGI on IIS7 - Simple page works inside, but not on the web]

Found the answer.

 

You need to make sure there are no ISAPI filters running.  If there is a PHP filter in place, FastCGI will not work outside.

 

Deleted the filter and everything came up perfectly.

 

 

[FastCGI on IIS7 - Simple page works inside, but not on the web]

Server:  Windows Server 2008 Web

IIS 7

 

PHP:  5.2

 

Can view a simple phpinfo page through localhost but I get an Internal Server error 500 when I try to see the same page through the full domain name:  sub.domain.com 

 

This is a new configuration so I am sure there is something I am missing in IIS7.

 

Checked log files, but I am not seeing anything that would tell me whats going on.

Situation:  New install of PHP on IIS7 FastCGI

Server:  Windows Server 2008 - Web Server

PHP:  5.2 Non thread safe

 

index.php script -  <?php phpinfo(); ?>

 

 

(all tests done from the server itself.  domain tests verified both on the server and outside of the network)

 

Test 1 - http://localhost/index.php      Works great.

Test 2 - http://localhost/subdomain/index.php    Works great.

Test 3 - http://sub.domain.com -  Internal Server error 500

Test 4 - http://sub.domain.com/index.php - Internal Server error 500

 

What the ****???
