The correct command line option for Daniel and me is /updateonce. There is no need of my previous batch file. I programmed the task manager to launch nettime.exe /updateonce at system bootup

Hi, I have the same need as Daniel: sync at boot and exit. I used the /synconly option but nettime keeps in tray. I have to wait 5 seconds and then kill process. I used the following command line code: start "" NetTime.exe /synconce timeout /t 5 /nobreak taskkill /f /im NetTime.exe I have to use start command because NetTime locks CLI if launched directly. I have to use force option (/f) in taskkill command because NetTime ignores termination signal sent by taskkill.
