Copy file to remote computer using remote admin credentials

Correct me if I’m wrong, but you can use LogonUser to impersonate a local group also not only domain accounts.

From the net:

Imports System 
Imports System.Runtime.InteropServices 
Imports System.Security.Principal 
Imports System.Security.Permissions 
Public Class Form1 
    <DllImport("advapi32.DLL", SetLastError:=True)> _ 
    Public Shared Function LogonUser(ByVal lpszUsername As String, ByVal lpszDomain As String, _ 
        ByVal lpszPassword As String, ByVal dwLogonType As Integer, ByVal dwLogonProvider As Integer, _ 
        ByRef phToken As IntPtr) As Integer 
    End Function 
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click 
        Dim admin_token As IntPtr 
        Dim wid_current As WindowsIdentity = WindowsIdentity.GetCurrent() 
        Dim wid_admin As WindowsIdentity = Nothing 
        Dim wic As WindowsImpersonationContext = Nothing 
        Try 
            MessageBox.Show("Copying file...") 
            If LogonUser("Local Admin name", "Local computer name", "pwd", 9, 0, admin_token) <> 0 Then 
                wid_admin = New WindowsIdentity(admin_token) 
                wic = wid_admin.Impersonate() 
                System.IO.File.Copy("C:\right.bmp", "\\157.60.113.28\testnew\right.bmp", True) 
                MessageBox.Show("Copy succeeded") 
            Else 
                MessageBox.Show("Copy Failed") 
            End If 
        Catch se As System.Exception 
            Dim ret As Integer = Marshal.GetLastWin32Error() 
            MessageBox.Show(ret.ToString(), "Error code: " + ret.ToString()) 
            MessageBox.Show(se.Message) 
        Finally 
            If wic IsNot Nothing Then 
                wic.Undo() 
            End If 
        End Try 
    End Sub 
End Class
