"cron" is usually mentioned as a Unix utility- which basically calls a script or a "one-liner" at any given time or interval listed in your crontab. I'm not sure if the actual cron program is available for NT- I just use Unix.

So ... if you have a unix box just try the man page:

%man cron

You may try:

%crontab -l

Which will list the current cronjobs for the current user.

%crontab -e

will edit the crontab. Make sure you do a:

export EDITOR=vi

so that cron knows which editor you use.
