I'm a noob working with Ajax-Enabled WCF Services... Right now I have an AJAX service which calls a different WCF service that is using wsHttpBinding. The WCF wsHttpBinding service lives in a different web app on the same IIS6 server. The AJAX javascript proxy is only created when I enable anonymous access on the app hosting the AJAX service. If I remove anonymous access, IE6 bombs with an 'Undefined' error when call the AJAX proxy. In a nut shell, my AJAX service sends a request back to IIS (same domain/app), and while on the server it sends a WCF service request for data on a different app on the same IIS server. The service returning data is setup with Windows authentication, wsHttpBinding, and security mode is set to message. Any ideas?

Both apps have are using windows authentication.
