Nice article!
I tried using this code for attempting to impersonate LocalSystem but with no success...
username was "SYSTEM", domain "NT AUTHORITY", empty password, Interactive LogonType, and Default LogonProvider.
But when calling LogonUser, i get the exception:
"Logon Failure: unknown user name or bad password. (Exception from HRESULT: 0x8007052E)"
Any ideas why this is happening? I run it as LocalSystem by the way...

I want to execute my console app from a Classic ASP page using WScript. The IIS website runs under network service, but I need the console app to run as local system. How do I get the CMD.exe test service to run my console app, without requiring user intervention?

Hi,

I'm facing out with a problem. Should read the Http 404 errors in IIS and I though your code was able to let impersonate the running anonymous user a Network service that can read that informations.
But I get denied access. Have you a particular idea?

Figured it out, I am a local admin of the local pc, but I am logging on with a domain account and I am setup as a domain user with the account. There is also a Deny policy on the local machine that has Users on it.

Huh. The only thing I can think of is that the con...

Huh. The only thing I can think of is that the console window that opened after you ran

C:\sc start testsvc

is not running as SYSTEM.

Try typing this into that console window:

C:\WINDOWS\system32>net config workstation

You should get an error like:

A specified logon session does not exist.

If you don't get an error (you'll see a listing that includes your user name) - try recreating the server and starting it.

If you do get an error, navigate to your .exe folder in the console window and run your assembly. If you've got System.Diagnostics.Debugger.Break() set, you should be able to break into the code to debug.

Hmmm, I am not able to impersonate the LocalSystem account... "don't have the permissions". Although I am a local admin on the PC, I can't get it to impersonate "SYSTEM".

//code start----->

MessageBox.Show(WindowsIdentity.GetCurrent().Name);
using (Impersonation imp = new Impersonation(BuiltinUser.LocalService))
{
MessageBox.Show(WindowsIdentity.GetCurrent().Name);
}

MessageBox.Show("done");

//code end----->

Any ideas...

Check out the static void Main(string[] args) entry point above - it gives an example of the impersonation class in use.

This is exactly what I am looking for. I need to shell out and run an application/cmd under the "SYSTEM" user context.

If possible, could you provide an example of the impersonation class in use.

ie. ... = new() etc.

Thanks!
