Creating a Citrix like Session with Powershell and RDP

I think this is worth noting for me creating a custom solution for Sandboxing an Environment full of domain admins.

Here are the interop’s if you need them, place them in the $dllpath that you choose.

Remove-Variable * -ErrorAction SilentlyContinue; Remove-Module *; $error.Clear(); Clear-Host
#Must run in x32 due to LoadAsm and the MSTSCfile
#Define Butten Click Function
$dllpath = 'C:\mstsc'
[system.reflection.Assembly]::LoadFrom("$dllpath\AxInterop.MSTSCLib.dll")
[system.reflection.Assembly]::LoadFrom("$dllpath\MSTSCLib.dll")
$rdp = New-Object AxMSTSCLib.AxMsRdpClient6NotSafeForScripting
[System.Management.Automation.ScriptBlock]$handleconnection = {
    # switch panels
    Write-Host "TADA!"
    #to stop run
    $timer.stop()
    #cleanup
    Unregister-Event thetimer
    }
Function DisplayHelloWorldText{
$Form.Controls.Add($Label)
$rdp.Name = "MyPowerShellRDP"
$rdp.Enabled = "true"
$ScreenBounds = [Windows.Forms.SystemInformation]::VirtualScreen

$rdp.AdvancedSettings7.AuthenticationLevel = 0
register-objectEvent -InputObject $rdp -EventName "OnConnected" -Action { Write-Host "&lt;TIMER&gt;" }

$action = {write-host "Timer Elapse Event: $(get-date -Format ‘HH:mm:ss’)"}
$timer.Interval = 3000 #3 seconds
