The call to the service returns promptly after delegating the job to a thread, before the task is completed. In the thread, "net stop dnscache", "net start dnscache", "ipconfig /flushdns" and "ipconfig /register-dns" are executed in that order. Parallel execution of these commands is prevented by a lock that is common to all connections started by the service. Note: "net stop .." is used instead of "sc stop.." as the latter can return before the service has fully stopped (in STOP_PENDING state), causing the subsequent start to fail.
