Ajax call fails under Windows Authentication

Ajax call fails under Windows Authentication

I have the following call to a WCF service working local to my machine, but when I deploy the code to the server which accepts only Windows access I can not figure out how to get credentials transported.  The binding is webHttpBinding
 
$.ajax({
type: "Post",
contentType: "application/json; charset=utf-8",
url: "EHSAuditWCFAjaxService.svc/GetAuditSearchData",
datatype: "json",
data: '{"inSearchWord":"' + inTextBox.value + '"}',
error: jqueryError,
success: success3
});
