Is there anyway to access network credentials with javascript without having to manually set them? This is needed in order to pass the credentials dynamically to a webservice. The webservice is setup for windows authentication and the browser is IE8.

Try the code mentioned here.
http://www.ureader.com/msg/16721933.aspx
<script language=javascript>   
  function getNTUsername(){
  
var wshNetwork = new ActiveXObject("WScript.Network");   
        alert('domain ='+   wshNetwork.UserDomain);   
        alert('machine name = '+   wshNetwork.ComputerName);   
        alert('user name = '+   wshNetwork.UserName);
        document.getElementById('username').value = wshNetwork.UserName;
        document.getElementById('UsernameDiv').innerHTML = 
wshNetwork.UserName;
  }
</script>   

Open in new window


However your HTML has to be saved with extension .hta and has to be loaded from hard disk

mplungjan, just for curiosity: how would a local stored .hta file be loaded/used by a page send from anywhere without violating the SOP?
(sorry for the silly question, as I'm no IE and M$ guru ;-)

You will need to "save/open" it from the web or copy it to your intranet users if that is what you need.

This won't work.  At best, the user will be prompted to allow on every page load. Check it out http://forums.asp.net/t/1124769.aspx

I believe I did.

What you are trying to do is a security risk, hence it only works on the lowest security level - that is when the user started the HTA him/herself

this cannot be done from a web page from a web server
