It is very likely to be a browser security related issue. Since yo can not rely on the client I would implement this redirection on server side. It looks that you are in a domain environment, thus you can easily check on server side if the computer is domain member or not.

But you can put it simply in a try catch block, like this:

JavaScript

function IP()
        {
         try
         { 
            var net = new ActiveXObject("wscript.network");
            alert(net.UserDomain+': '+net.ComputerName);
            alert('SUCCESS');
         }
         catch ()
         {
            window.location.href="Welcome.aspx";
            return true;
         } 
        return false;
       }

i tried this

C#

try
        {
           var net = new ActiveXObject("wscript.network");
           alert(net.UserDomain+': '+net.ComputerName);
           alert('SUCCESS');
        }
        catch(err)

        {
           window.location.href="Welcome.aspx";
        }

it's successful
