无法通过ajax调用访问服务器中托管的Wcf服务，但可以访问本地计算机中托管的相同Wcf服务

**And this is the ajax call I have made:**

        var data = { 'logindetails': { 'UserName': UN, 'Password': PW } };
        var st = JSON.stringify(data);
        debugger;
        $.ajax({
            type: "POST",
            url: "http://192.168.4.89/mob/AppService.svc/GetUserAuthendication",
            data: st,
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function (result) {
                ServiceSucceeded(result);
                //// Play with response returned in JSON format
            },
            error: function (jqXHR, textStatus, errorThrown) {
                alert(jqXHR + "-" + textStatus + "-" + errorThrown);
            }


        });

When I host my Wcf service in my local IIS and make an ajax call from my local machine itself, its working fine, but when I host my Wcf service in server and make an ajax call to that Wcf service hosted in server, from my local machine, I couldn't access it.
Please go through this code and help me in finding the problem
