Hi,
On Windows (2000 or newer) using IE6+, is there a way in javascript--without calling some ActiveX--to get the windows network login name on the client computer? If so, how would I do that.

If not, is there an ActiveX call that would do this? This is for an Intra-net web application, so I have some control over the clients, but we still want to avoid opening ActiveX even to intra-net zones.
Thanks,
--Jim

this worked for me...

Code: 
<%
Dim sFullUser
Dim iPos
Dim sDomain
Dim sUser
Dim objUser

     sFullUser = trim(Request.ServerVariables ("LOGON_USER"))
    iPos = InStr(sFullUser, "\")
    sDomain = Left(sFullUser, iPos - 1)
    sUser = Mid(sFullUser, iPos + 1)
   
    Set objUser = GetObject("WinNT://" & sDomain & "/" & sUser)
%>

<html>
<body>
This is your name: <%=objUser.FullName%>
</body>
</html>

which i got from here.

Version using ActiveXObject.
[tt]
var wshnetwork=new ActiveXObject("wscript.network");
var suser=wshnetwork.username;
var sdomain=wshnetwork.userdomain;

Thanks,
The ActiveX works, but I will have to set a policy to allow 'not marked as safe' activeX controls, which will have to do.

The ASP thing would be ok, but I'd tried that and it returns a blank--I'm guessing that's because the browser can't fetch the "Logon_Name" unless the browser security allows it? Anyone know if this is true? It would have to be something other than the ActiveX settings that would allow this, because after I set the 'Allow Activex not marked safe', the ASP Servervariable still returned a blank. I guess I can see why, otherwise anyone surfing the internet would be giving out network usernames to any site that wanted it.

If you prefer server-side variable approach, you need to set the server, rather than anything on the client, so as to exige integrated authentication and to disallow anonymous access.
