Trying to pull registry values from remote domain machines to see who last logged on.

So I have a couple of fields for username, pass and computername..Based on that data I am trying to view the registry of the remote machine and pull this key...Currently I do this in Powershell...

C#

[Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey("LocalMachine","remotepcname").OpenSubKey("SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI").getvalue("LastLoggedOnUser")

string Username;
string Password;
String Computer;
Computer = txtIP.Text;
Username = txtUsername.Text;
Password = txtPassword.Text;

What I need is when I execute a button that it fills in those variables for Admin auth and the computer name and pulls that value into txtResult field..

Sorry I am new to C# so I really appreciate any help! I found some stuff on google but I am not quite there yet... Thanks again! :)

Solution 1

Doesn't OpenSubKey() return the values you need?

It returns a RegistryKey object. You should probably get the info you need from the returned object.

Ended up going w/ RegistryKey.OpenRemoteBaseKey

I.e.
RegistryKey hive = RegistryKey.OpenRemoteBaseKey(RegistryHive.LocalMachine, remotemachine, RegistryView.Registry64);

//sample

C#

//Clears last run result
            txtResult.Clear();
            //Begin Error Handling
            try
            {
                //Sets variable for remote machine field
                string remotemachine;
                remotemachine = txtComputer.Text;
                // hourglass cursor
                Cursor.Current = Cursors.WaitCursor;

                //Begin Code to check Registry
                RegistryKey hive = RegistryKey.OpenRemoteBaseKey(RegistryHive.LocalMachine, remotemachine, RegistryView.Registry64);
                var key = hive.OpenSubKey(@"SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI");
                if (key == null)
                {
                }
                object oVal = key.GetValue("LastLoggedOnUser"); if (null != oVal)
                {
                txtResult.Text = oVal.ToString();
                //Return Curson
                Cursor.Current = Cursors.Default;
                //End Registry Check
