How to know the remote user uses a concrete Windows domain name

Question

I'm trying to develop a Java Web App to know if an user that access to the server is using a computer configured with a concrete Windows domain.

What I need to know is the name of the remote domain, as the value I get with this:

System.getenv("USERDOMAIN");

Is it possible?

Thanks.

The domain name is not the same as the OS the person is running... I don't think the domain name is sent in the user agent. — Sumurai8, Feb 11 '16 at 08:35

You can get the User-Agent from the header of the user's HTTP request:

String userAgent = request.getHeader("User-Agent");

And there you have all the info you need: OS, browser, etc.

You can rely on these links for better understanding of the User-Agent info:

EDIT

What you could do in order to retrieve the user's domain name is:

retrieve the IP address from the request (use this and this answers as a starting point)
after having the host's IP address, you could retrieve the host's domain name like its explained here

With this I only can know if user is connecting from a Windows system, but I can't know the domain's name – Carlos Durán Feb 11 '16 at 08:11
@CarlosDurán, please check my updated answer – António Ribeiro Feb 11 '16 at 08:45
Thanks @aribeiro, but this solution only works if the computer is connected directly to the LAN; but if it is connected through a VPN connection, I only can retrieve the IP, not the domain (or the workgroup). – Carlos Durán Feb 11 '16 at 12:27
