Why are my web service methods only available from the server?

[Thesisus]

The web service works, but the methods are not available from a remote machine. Instead I get this "The testservice form is only available for requests from the local machine.". I've done this before, just messing around and it all went perfectly. Now that I'm under a deadline and actually working on a project I've run into this little nusance; any help anyone? Fear not my insanity, fear the mind it protects.
