Testing .NET Web services remotely is disabled by default. This means that if you navigate to a Web service and select a method, you will not get the HTML form for testing the method unless this has been enabled as described in this article. The trick is to add the following section to Web.config:
<system.web>
<!--
The following enables access to the test forms
from a remote machine.
-->
<webServices>
<protocols>
<add name=″HttpGet″/>
<add name=″HttpPost″/>
</protocols>
</webServices>
...
</system.web>
