I need to re-direct users to different pages depending on what version of windows they are using.  I  have been using the following command to try and see what version is there

<script language="JavaScript">
  var detect = navigator.userAgent.toLowerCase();
  document.write(detect);
</script>

... this returns....

mozilla/4.0 (compatible; msie 6.0; windows nt 5.1; .net clr 1.0.3705)

.. however I am running Windows XP Professional! does anyone know why it would find windows NT 5.1?  is there a different command I should be using?

Obviously I have very little knowledge of Javascript, and any assistance would be helpful.

Thanks,
Paul

NT5 is an internal name for XP

(What if the user isn't running Windows at all?)

Hi pwill40,

You are getting the base version of windows.

You can do a comparision something like this
if version > 5.1 => windows xp
if version = 5.0 => windows 2000
if version = 4.0 => windows NT

Here is a complete listing.
