JQuery AJAX Call to MVC action , asking the Credentials in Windows Server 2008R2

I have a jquery ajax POST to a MVC Action (which returns action result). In that i retrive record from DB and store in Session and return partial view result . On my machine this works well, when deployed it in Windows Server 2008 R2 , A popup appears in the browser asking me to enter credentials (authentication required).

The jquery call:
---------------

var data = $('#SearchForm').serialize();

           window.location.hash = '#/' + data;

           $.ajax({
               url: '/PromotionManagement/PromotionsSearch',
               type: 'POST',
               data: data,
               beforeSend: function (xhr) {
                   $('#search-result').hide();
                   $('#divresetCancel').hide();

                   $('#divwait').show();
                   // console.log('before sending request...');
               },
               error: function () {
                   //console.log("error processing request...");
               },
               success: function (data) {
                   debugger;
                   //console.log("successfully processed request...");
                   $('#search-result').html(data);
                   $('#search-result').show();

                   $('#divwait').hide();
                   $("#validation").html("");

                   if ($(data).html() == '\n        No Records Found \n    ') {
                       $('#divresetCancel').hide();
                   }
                   else {
                       $('#divresetCancel').show();
                   }


               }

           });

MVC Action :
------------


[HttpPost]

public ActionResult PromotionsSearch(string list,string query)
    {
    
    //code to retrive the data from DB.
    
     Session["SearchPerameters"] = objSearchPerameters;
    
     return PartialView("PromotionsGrid", Promotions);
    
    }

I referred [this][1] link and stopped storing the data in Session.
Even though it didn't work .

Can you pls suggest me what is missing..

any help can be greatly appreciated.
