Start and impersonate a console app from windows service

Hi,

I posted a question earlier asking about starting a process as a different
user from windows service. I got some replies and read about this a bit
more on the web but still couldn't get it working.

The application I want to start is a console app and it also opens a win
form which contains an axWebBrowser. There is no user interaction with the
form.

I've tried creating a Process and set the username, password and domain in
the Process's StartInfo:

    Process p = new Process();
    p.StartInfo.FileName = "somePathToThe.EXE";
    p.StartInfo.Arguments = "some arguments";
    p.StartInfo.UserName = "theUser@Domain";
    p.StartInfo.Password = passwordInSecureString;
    p.StartInfo.UseShellExecute = false;
    p.Start();

I've also tried Pinvoke the CreateProcessWithLogonW Windows API call. I
read about having to set the default desktop for console application so I
did this: startupInfo.lpDesktop = @"winsta0\default";

These 2 methods both did not work. I got this message as soon as the
process starts: The application failed to initialize properly (0xc0000142).
Click on OK to terminate the application.

If I start this application without the impersonate, it works perfectly. I
won't see the console and win form showing up but I see the expected result
when the app ends.
Only when I add in the impersonate, I get the error message every time when
the windows service tries to start my application.

Also I have a console app which does the same thing as my win service. If I
try the impersonation in the console mode, it works. Only when it runs from
win services, it gives the error.

Is there other way to do this? Or am I missing something in my code??

Thank you!!

What happens if you run the service using a System or Administrator account?

When running service as Local System Account, I got "access is denied" error
or Win32 error code 5 which is the same error "Access is denied".

When running as admin or normal user account, it shows the "application
failed to initialize properly" error. :(

Have you tried running it as the same user with which you're logged on?
Also, did you set the option to allow the service to interact with the
desktop?

yup, I tried running as myself and I am also the admin on the machine but
it's still not working.

I see that I can only set that option if I use the Local System account to
run the service. From the service property window, I don't seen an option
to enter a user logon and select the allow service to interact with desktop.
Is there other way to set this up??

Thank you very much for your help!!!

I have just tried changing the LogonFlag of the CreateProcessWithLogonW
method from LOGON_WITH_PROFILE to LOGON_NETCREDENTIALS_ONLY.

It started the new process properly but then I realised the process was not
running as the new user, it's using the user credential for network only.

So windows service has no problem starting a new process. But if the
process has to be started as a different user, it gives that error.

Is there some permission thing that I need to setup before creating the
process?? Has anyone tried this before?

Thanks in advance!!!
