Get the full path of an Application when it is started through a LAN

[code]
var
  PathExe: string;
begin
  PathExe := ExtractFilePath(Application.ExeName);
[/code]
//.....................................................................

I have no problem when the Application is ran on a Local Computer to get its path ....
But I need to get the full pat when I start the Application through a LAN.
Thanks !
Emil.
