PHP is a server side language - it will read headers and form
data sent by the client browser, but it cannot request the data. That kind of information is not transmitted with the HTTP headers.

If the web server is in the same domain, i.e. intranet, try echoing
$_SERVER['LOGON_USER'] and $_SERVER['AUTH_USER']. Might only work with IE.

You might have more success asking in a Windows and/or IIS forum, as to how
you can get the user name into the server environment.

There are alternative ways of achieving what you're after:

You will need to ask the users (user) name by way of form, js popup etc....

And then...

Store a cookie in the users computer.
And on subsequent visit, just retrieve that cookie.


OR

Store the details on your server, along with the users IP address so that on subsequent visit the user can be identified by IP address.
This method work only where users IP does not change
