anonymous-access

Hi everyone, I use a CascadingDropDownList of the AJAXControlToolkit in a ASP.NET MCMS 2002 web application. The CascadingDropDownList works as expected until "Anonymous access" and "Integrated Windows Authentication" flags are both checked (and this is the situation in the production environment) in the Directory Security settings on the website under IIS.

The error I get is: 500 Internal Server Error No web service found at:

If I uncheck the anonymous access or the windows authentication everything is ok.

Any suggestions?
