SOON 3600 "%0"
This re-schedules your batch file to run again in 3600 seconds (one hour). To start the process, use the SOON or AT command.
To Stop it from rescheduling, type AT to get the current ID and then type:
AT \\ComputerName ID /DELETE
You could get a good scheduler like OpalisRobot, which allows scheduling granularity in seconds and/or hours and/or days.
