I've installed Apache 2.2 server and PHP 5.3 on Windows XP SP3. After the initial install, Apache loaded the test page, i.e.,

http:/localhost (C:/Program Files/Apache2.2/htdocs/index.html) showed "It works!".

After configuring Apache and installing PHP, trying to load http:/localhost/phptest.php i.e. (C:/testsite/htdocs/phptest.php).

But this throws an error:

Not Found. The requested URL /phptest.php was not found on this server.

I also get the same error now loading

http://localhost

httpd.conf edits:

ServerName localhost:80

DocumentRoot "C:/testsite/htdocs"

<Directory "C:/testsite/htdocs">
    Options FollowSymLinks
    AllowOverride None
    Order deny,allow
    Deny from all
</Directory>

<IfModule dir_module>
    DirectoryIndex index.html index.php
</IfModule>

LoadModule php5_module "c:/testsite/php/php5apache2_2.dll"
AddType application/x-httpd-php .php
AddHandler application/x-httpd-php .php
PHPIniDir "C:/testsite/php"

File php.ini edits:

include_path = ".;C:\testsite\php\includes"
extension_dir = "C:/testsite/php/ext/"

System path:

The PHP directory was added to the Windows path, e.g.

PATH=C:\Windows\System32;C:\many_dir;C:\testsite\php

The only errors in the Apache error.log are:

Warning: DocumentRoot [C:/Program Files/Apache Software Foundation/Apache2.2 /docs/dummy-host.localhost] does not exist
Warning: DocumentRoot [C:/Program Files/Apache Software Foundation/Apache2.2/docs/dummy-host2.localhost] does not exist
Warning: DocumentRoot [C:/Program Files/Apache Software Foundation/Apache2.2/docs/dummy-host.localhost] does not exist
Warning: DocumentRoot [C:/Program Files/Apache Software Foundation/Apache2.2/docs/dummy-host2.localhost] does not exist

The Apache service restarts successfully and is running. I can't find anything amiss. Can anyone spot any stupid errors?
