Hi Landon,

Thanks for your posting. From your description, you've a .net based NT
service in which you use the
Process.Start to create a new process to run a certain application(exe)
which will acess the sound card and USB device. But you found the that new
process will crash. And if you run the exe app via double clicking , that's
ok ,yes?

As for such problem, I think it is likely concerned with the aft.exe app.
Does this app need to run in a UI context or have interactive processing?
Since the windows service / asp.net service application are all
non-UI/non-interactive based, start interactive applicaitons in them will
cause many unexpected errors.
Also, as for the security you mentioned, is your NT service run under a
powerful account or a restricted account?

In addition, you can also try set the ProcessStartInfo's
CreateNoWindow = true
UseShellExecute = false

to see whether it'll help.
