whats the substitute of cron (in linux) in windows 2000 server? is it the autotask thing, or are there any kind of new softweare you need to download?
No, just use task scheduler. Probably have to make a batch file to run the job, and just schedule the batch file.
at is your friend.
Try running that command on the command line of a 2000/XP (?)/2003 (?) machine.
