Anyone has ever come accross an error



The error sometimes is 500, sometimes 12030...

When opening the web service in a browser and invoking the method, it executes just fine.
If the page calls the web service using ServicePath of the CascadingDropDown ajax control, the Target control returns the Method Errors. It is intermittent, sometimes it is 500 and sometimes it is 12030.

I have attempted to fix it by:

• making the web service method as static
• uncommenting the code in the web service to allow it to be called by asp.net script
