How can I get the domain name and username?

[Cherry Adriano]

I'm new with .net programming....so pls bear with me. May
I ask how can I get the domain name and username of user
who is trying access my web application.

 

[Chris Jackson]

System.Web.HttpContext.User.Identity.Name will return a string in the form
domain\userName.

Hello Cherry,
Add this to your web.config file. This file is in the solution files in
Visual Studio .NET.
<identity impersonate="true" />

Then you can use this line of code.
System.Security.Principal.WindowsIdentity.GetCurrent().Name)

I hope this helps you.

Sir Chris,
System.Web.HttpContext.User.Identity.Name returns
domain\username where domain is my computer name and
username as ASPNET. Do you know how can I get network
logon name(username) and domain used in logging on to
Operating System?

There is a way to get the network logon name using vb6 .
See VB6 script below. How can I get this in VB.net Thanks
=)

Private Declare Function w32_WNetGetUser Lib "mpr.dll"
Alias "WNetGetUserA" (ByVal lpszLocalName As String, ByVal
lpszUserName As String, lpcchBuffer As Long) As Long
Private Sub Form_Load()
'KPD-Team 1998
'URL: http://www.allapi.net/
'E-Mail: (e-mail address removed)
Dim lpUserName As String, lpnLength As Long, lResult
As Long
'Create a buffer
lpUserName = String(256, Chr$(0))
'Get the network user
lResult = w32_WNetGetUser(vbNullString, lpUserName,
256)
If lResult = 0 Then
lpUserName = Left$(lpUserName, InStr(1,
lpUserName, Chr$(0)) - 1)
MsgBox "The user's Network Logon Name is " +
lpUserName + ".", vbInformation + vbOKOnly, App.Title
Else
MsgBox "No user found !", vbExclamation +
vbOKOnly, App.Title
End If
End Sub

Hello Cherry,
Did you add <identity impersonate="true" /> this to the web.config file and
you need to have windows integrated select too in the directory security of
your application root.
Thank you,

Sir Chris,

NICE! I have been knighted!

John's answer is absolutely correct, this pulls the user token that is being
used by the process for external calls. You have to have BOTH ASP.NET and
IIS configured for Windows Authentication. The complete identity matrix can
be found here:

I already added <identity impersonate="true" /> to the Web.Config file, however, error similar below was encountered

"An error occurred while try to load the string resources (GetModuleHandle failed with error 126)."

Please help. thanks =)

Grant ASPNET account "Impersonate a client after authentication" privilege.
