user account name of computer from ip address in C#

Question

I need to track which user account on the same pc is using my software which is an web application. Is this possible? I can only get computer name but not user account name. I need to find out whether it is administrator or guest.

Answer 1

I think the only way to achieve this is by using Windows Authentication in you web application. Then you can check all claims available to this user.

Note : For this to work the server and the client must be on either the same domain, or domains with trust between them.

Answer 2

I tried this code and it worked perfectly.

public static string GetIP4Address()
    {
        string IP4Address = String.Empty;

        foreach (IPAddress IPA in Dns.GetHostAddresses(HttpContext.Current.Request.UserHostAddress))
        {
            if (IPA.AddressFamily.ToString() == "InterNetwork")
            {
                IP4Address = IPA.ToString();
                break;
            }
        }

        if (IP4Address != String.Empty)
        {
            return IP4Address;
        }

        foreach (IPAddress IPA in Dns.GetHostAddresses(Dns.GetHostName()))
        {
            if (IPA.AddressFamily.ToString() == "InterNetwork")
            {
                IP4Address = IPA.ToString();
                break;
            }
        }

        return IP4Address;
    }
