Use the alternative, this worked fine for me.
[php]
ShellExecute( NULL, "open", "C:\\WINDOWS\\system32\\cmd.exe","/C ipconfig/release",NULL, SW_SHOWNORMAL);
[/php]
That's the same as typing
[php]cmd /c ipconfig/release[/php]
in that little 'run' program.
Good luck with your tapper.

cuz it might be system() and not System() >_> or whatever...
