ASP .NET Ajax Client -side framework failed to load

[Thejaswini]

Hi,

While running application from VS2010 Ajax Accordion control works fine, but when we host the web application on IIS it is giving the below errors and application behaves differently:

1. ASP .NET Ajax Client -side framework failed to load

2. 'Sys' is undefined


Can anyone pls help me to resolve this issue ASAP as it is critical.

Thanks for your help!!

Thanks,
