Site not working on IE9 for production server

[nitin_ion]

My site is working on QA and Dev server for IE9 but not for production server. All the servers are windows 2012. can anyone point what can be the probable cause?

I am not sure what, if anything, this has to do with C#, but you are asking people to make a guess based on no useful detail of your problem.

Yes. Your production setup is different to your QA and Dev setup. Beyond that, without any actual details of what isn't working, you're not likely to be able to get much more help. BTW - this isn't really a C# question.
