Hi Bearfoot,
GoDaddy places serious limitations on some of their Windows servers that prevent more complex PHP applications from functioning. So to dig a bit further:
1. Can you determine if the server is running IIS v6 or v7, please?
2. Can you post or MSG me the server path to where you’ve installed EE? This will be a windows-type path (e.g. c:\inetpub\wwwroot\), it will NOT start with http.
Do help determine this, you can create another test file named ‘whereami.php’ that should output the real path to itself. Place it in the site root. It’s a single line:
<?php echo realpath(dirname(__FILE__)) . '/'; ?>
3. Are you certain you have ruled out switching to a *NIX server? This is going to be a better option in the long run, honestly.
