Ajax controls are disable in IE

Hi everyone,

I am new to web developing. Been working on a project for about 4 months or so to be used inhouse at the company I work for.

I am using WEb express 2012 for my development.

I created a intranet website using the ajax toolkit controls such as the calendar extendar, shadow extender, collapsiblePanel ext. etc.

When developing the wesite I have no issues running in IE9/10/11. When I imported the application to a windows 7 (64bit) machine running IIS7 the controls using those extendars are not working.

They seem to be disabled. In Fixrefox and  Chrome they work as expected.

In IE 9 I was able to get the controls(extenders) to work after I disabled the interanet zone settings.

Is this a bug or is there something I am missing?

Thanks
