I have implemented the an AJAX enabled Web Service for my combo box exactly as explained here:
http://www.telerik.com/help/aspnet-ajax/combobox-load-on-demand-wcf-service.html
http://demos.telerik.com/aspnet-ajax/combobox/examples/loadondemand/wcf/defaultvb.aspx
It works perfectly on my development server running IIS7.5. When I run it on my remote test server also IIS7.5 - I get a 401 error. The rest of my ASP.NET4 web app works fine. Using Fiddler I find I get a 401 Unauthorized error - the inner exception being "Authentication Failed" System.InvalidOperationException. The IIS log shows 401 0 0 after the POST to my web service, i.e. a sub error code of 0. I think this relates to "Access is denied due to invalid credentials"?
This post sums up my problem:

But as you can see no answers.
I've spent a long time looking into this with no luck and I'm really running out of ideas. It must be down to some IIS configuration or permission or something similar. Has anyone had this problem before of know how to resolve it? Thanks

Hi,
Thank you for contacting us.
Indeed the experienced problem seems like a configuration issue withe the permissions. In general the WCF service which the RadComboBox consumes should have permission for anonymous access.
Please try to add the following lines in your web config file:
Please note that the above configuration is using some dummy name for the WCF service, so you should change it with the name of your service.
Kind regards,

Thanks for the reply. I had included those lines already - it made no difference.
I spent 3 days trying to get to the bottom of this - Googling various forums - and finally had to accept defeat reluctantly, so I found another way around the problem using LinqDataSource as shown in: http://demos.telerik.com/aspnet-ajax/combobox/examples/loadondemand/automaticloadondemand/defaultcs.aspx
It seems a little slower (I have a lot of data) but is an acceptable solution. I would still be interested to know the solution to the problem if anyone can figure it out.
