If you're in a domain environment you could enable Windows Authentication which will allow the users to bypass explicitly logging on in favor of NTLM authentication. IE and Chrome work well with this out of the box, FF has a config setting for it.

EDIT

If you only care about browsers/OSs that support ActiveX then you can get it using Javascript with specific ActiveX privileges (from here ):

<script type="text/javascript"> 
<!-- 
var WinNetwork = new ActiveXObject("WScript.Network"); 
alert(WinNetwork.UserName); 
//--> 
</script>

It seems ServerVariables have been depreciated for C# in some instances.

If so, you'll need to do it this way:

string login = System.Security.Principal.WindowsIdentity.GetCurrent().Name;

If you really want to use ServerVariables, keep in mind they are CaSe Sensitive in C#. The correct casing is almost always UPPER , and here is the list of them:

Try this Might be its work as per your requirement

Request.ServerVariables["LOGON_USER"]

if Request.ServerVariables("LOGON_USER") Returns Empty String in ASP.NET Microsoft Guidline for that

Answer 4

You can use Request.LogonUserIdentity for getting client details.

Response.Write(Request.LogonUserIdentity.Name);
