Hi All,

I'm trying to wrap Powershell in C# for a SSH server implementation
but I am getting the following message:

Windows PowerShell terminated with the following error:
Access is denied. (Exception from HRESULT: 0x80070005
(E_ACCESSDENIED))


To start Powershell I am impersonating another user like so:

WindowsIdentity windowsIdentity = (WindowsIdentity)
identity;
windowsIdentity.Impersonate();

ProcessStartInfo psi = new ProcessStartInfo()
{
WindowStyle = ProcessWindowStyle.Hidden,
CreateNoWindow = true,
RedirectStandardError = true,
RedirectStandardOutput = true,
RedirectStandardInput = true,
UseShellExecute = false,
ErrorDialog = false,
WorkingDirectory = @"C:\windows
\system32\WindowsPowerShell\v1.0\",
FileName = @"C:\windows\system32\WindowsPowerShell
\v1.0\powershell.exe",
Arguments = "-i Text -NoExit -Command -"
};

_childProcess = Process.Start(psi);

Does anyone have any idea why this is not working? What sort of
permission would Powershell be requiring to start up?


Thanks in advance,


Luke

I'm curious as to why you are starting PowerShell as a new process rather
than hosting it within the application as shown here
