Sys is undefined error Ajax 1.0

User-117359044 posted
Hi
We have an old website on .NET framework 2.0 with Ajax 1.0 (AjaxControlToolkit.DLL version 1.0.11119.0). It used to run fine for few years, We recently moved this website to a new Windows 2008 server (.NET framework 4.0). The website works fine but whereever Ajax was used it shows up a message 'Sys' is undefined. I found numerous info on web about this error, but none worked for me. I certainly am missing something.
I checked the bin folder for the AjaxControlToolkit.dll and web.config for the required entries.(infact everything just copied from old machine win 2000 server)
One observation is, when i run the website from IDE (Press F5) (using localhost:3508/Website/Webpage.aspx) the Ajax works perfect, but when i run it via IIS it does not work and shows the error.
Please someone suggest what is missed and what needs checking.
Thanks
John
