WCF: The server method 'MyMethod' failed - wcf

Question

The WCF service is deployed on different machine.
Im able to get the http://MyServer/MYService.svc/jsdebug file by giving
<identity>
<dns value="ServerName and the portnumber"/>
And I'm able to invoke the service method using javascript.
After invoking the MyMethod.
I get this error in the javascript --> The server method 'MyMethod' failed, status 404 (in failedCallback)
MyMethod returns a Boolean value in svc.cs file after performing a datacheck.
These are the errors came up when I used Firefox Firebug:
When I call the same service using VS2008 in my development environment it works fine.
I found that following are the files which are not loading while using Ajax enabled VS2005
1) MicrosoftAjax.debug.js(3.5)
2) MicrosoftAjaxWebForms.debug.js(3.5) During runtime
Its obvious that 3.5 debug files doesn't load but, 1.0.6 debug files should load without the errors displayed below.

Appreciate your inputs.

Answer 1

Seeing as you have Firebug installed, you can use it to check the HTTP request and response to see if they contain more information about what went wrong.
