Get Client Computer Name

I'm attempting to retrieve the client computer name from my ASP.NET web application. I'm using System.Net.Dns.GetHostName(). This is returning the computer name of the web server. The application is being used an a Windows 2000 Active Directory Intranet.

How do I get the name of the client computer, not the web server name?
Thank you.

Try either

Request.ServerVariables["REMOTE_HOST"] for the client computername
Request.ServerVariables["REMOTE_ADDR"] for the client ip address

Request.ServerVariables("remote_addr") and Request.ServerVariables("remote_host") both return the IP address of the client.
Now if I could just get the computer name of the client...

Here's one way to do it.

Dim computer_name() As String
computer_name = Split(System.Net.Dns.Resolve(Request.ServerVariables("remote_addr")).HostName, ".")

I know this is an an ancient thread, but its the one I found that helped me.

string[] computer_name = System.Net.Dns.GetHostEntry(Request.ServerVariables["remote_addr"]).HostName.Split(new Char[] { '.' });
            String ecn = System.Environment.MachineName;
            txtECN.Text = computer_name[0].ToString();

 The above is the updated (non deprecated) version of this post in C#

Works like a charm for me where my users my be at several different computers in one day.

 I'm trying to do similar things for all my client computers. However, I need to get the MAC address of the client computer too. How can that be done?

8/26/2008 4:02:07 PM This post should handle the basics.  Be aware that this particular link grabs the first MAC address that it finds in the machine.  I haven't attempted to deploy this code to a website yet, only used something similar in desktop packages.

The above code does work in web application aspx pages.  It does not work in web service asmx pages.  For web service


 function returns the client computer name.

The original poster and I both wanted to obtain the client computer name.  The above codes work for web application and web service pages with a local server.  However, these codes did not work when I applied them to my remote server.  Like the original poster, I only gathered the Web Server name. 

I do not believe that it is possible to obtain the client computer name from a remote server.

try this:

Request.UserHostName, this will return the machine name of the client that is sending a request for the application.
