Using WScript to get user name and domain name in IE

The following codes show how to retrieve the user name and domain name from javascript code. The follwoing code is quite straight forward however a developer has to consider the following before using this code.

• The code uses the built-in ActiveX object of IE which of course will only work for IE browsers.
• Some browser security policies may not allow this implementation as this requires trust settings

    <form id="DefaultForm" runat="server">
        Authenticating user. Please wait...
        <input type="hidden" id="UserName" name="UserName" /><input type="hidden" id="Domain" name="Domain" />
        <script type="text/javascript">//<!--
            var netw = new ActiveXObject("WScript.Network");
            window.document.DefaultForm.UserName.value = netw.UserName;
            window.document.DefaultForm.Domain.value = netw.UserDomain;
            window.document.DefaultForm.submit();
        //-->
        </script>
    </form>
