Retrieving Client Computer Name

I attempting to retrieve the user name and client machine name of the person logged on to a computer on our intranet in ASP.NET. This is just for logging purposes. I am able to retrieve the user name easily enough via "User.Identity.Name" or "System.Security.Principal.WindowsIdentity.GetCurrent().Name", however I cannot get the CLIENT machine name. I have searched high and low and everything I have tried returns the machine name of the server. Any suggestions? Much appreciated!

AntarcticAlicia, I did look for a solution, but
I couldn't find one.[V]
Should this be a security issue ?
Possibly, you can try in the Command window
the "net" and the "nbtstat" commands.
You get the possible options with /? as parameter.
Good luck.

I played a bit with the command window.
If I input "net view", then a list with computer
names active on my LAN results. With
"net view > pcnames.txt" you get the same results in
that specified file.
A script could take care for this command and
thereafter use these computer names to search for
the associated user names in the next way.

' Returns the user name of the user currently logged on
' to a remote computer. To use this script, replace
' RemoteComputer with the name of the remote computer
' you want to check.

' Script Code

strComputer = "RemoteComputer"
Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colComputer = objWMIService.ExecQuery _
("Select * from Win32_ComputerSystem")
For Each objComputer in colComputer
Wscript.Echo objComputer.UserName
Next

I hope you can use this idea.

Perhaps a WMI call to the IP address of the incoming session?

On Error Resume Next
strComputer = "111.222.33.4"
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
Set colItems = objWMIService.ExecQuery("Select * from Win32_ComputerSystem",,48)
For Each objItem in colItems
Wscript.Echo "Name: " & objItem.Name
Next

I HAVE A SOLUTION! Thank you so much for the suggestions. I have not tried them yet but I plan to do so to see if they will work for me. For now I wanted let you know that I found something else that finally worked for me:

Dim host As System.Net.IPHostEntry
host = System.Net.Dns.GetHostByAddress(Request.ServerVariables.Item("REMOTE_HOST"))
strComputerName = host.HostName

I suppose I was trying to make it too difficult. Thanks for everything! ~Alicia
