Why Remote Process is not launching from WCF call to Process.Start in interactive mode?

Question

0.00/5 (No votes)

See more:

I have WCF service which launches the remote process from Process.Start successfully on stand alone machine where this WCF service is hosted/deployed and developed.

I deployed this as whole service on another machine, and run the service on that machine as well, execute the service on the same code area which launches the process remotely, here it failed, Strange behavior.

I checked the process state stand alone , and launched the process normally, it executed fine and shown the message box inside that process which was written there.

BUT when this process launched via WCF call from code, process didn't launched in interactive manner, Task Manager shown the launched process, but its console not shown, nor any message box shown . ANY IDEA ? or WAY AROUND?

Note : This behavior is observed when WCF service deployed completely with all binaries on another machine.

Usman

Put a try/catch block around the wcf code that launches the app, and have the wcf service method return the exception that's occurring.

I think that's the only way you're going to find out what's going on.

You can also check the system logs on the server in question, but I doubt that's going to be helpful.

Solution 2

It's not strange at all if you think about it. It would be a HUGE security risk to be able to launch an interactive process remotely. So, Windows does not allow you to do that. It's that simple.
