I don't know how you would do this on a win system but us nix users, we can use the native hostname with -f to get a reliable hostname. <?php $_SERVER["SERVER_NAME"] = exec('hostname -f'); ?>

You can use php_uname("n") in Windows to return the host name. You may have worked this out already but it took my a blinkin age!

It looks like this function isn't available on windows. Here is my code: <?PHP $var = gethostname(); IF ($var===FALSE) { echo "The function ran but no results were returned!"; } ELSE { echo "The function returned a value\n\r"; echo $var; } ?> I received an error: "Fatal error: Call to undefined function gethostname() "
