Has anyone run into this issue? The application runs perfectly on a 2003 Server IIS6, but on Winhost IIS7 it will not properly load. It seems to be an AJAX enabling issue. I have added all the suggested entries to the web.config that GOogle has to offer and even turned forms authentication off in case it was an access issue, but nothing seems to work.

The error message is not enough to find out what is the cause of the problem. Try downloading and installing Fiddler on your computer. It is a program that records out bound http calls to the server. This should give you a better understanding on what is occurring on the back end. http://www.fiddlertool.com/fiddler/version.asp
When you pull up the site, it should start recording the http calls. Find anything that is 400 or 500 status errors.
Any update to this? I'm interested in this solution as I am recieving the 'sys undefined' error as well, although I do have the 'ASP.NET Ajax client-side framework failed to load' issue solved (updated my web.config). Everything works locally but not on Winhost. Is there any specific configuration I need for 3.5?
This is such a hard error to figure out because it doesn't give you enough details to even know where to start. The problem can occur in all sorts of places. Another good technique to debug this is to start off small. Debugging a fully developed application is very difficult to do.
