Have you ever had the need to test and run a webservice from a machine other then localhost (127.0.0.1)? I was recently debugging a webservice that was running fine locally and when run from the production server it was behaving unexpectably. I remember reading a blog a while back showing how to remotleyy run a webservice. Remeber you will only want to do this for testing only and then turn it off in production.

Add this to the <system.web>
<webServices>
<protocols>
<add name="HttpPost" />
<add name="HttpGet" />
</protocols>
</webServices>
