i'll gladly answer this question if you can remind me how to use 'at' or whatever other scheduler you are using on your windows machine...
i'm generally using cron, so i think the win32 equiv is 'at', right?
your ftp .bat should look something like this:
#
ftp -s:servername IP.address
user .username passwd
binary [or whatever mode you want]
get path/to/file.xxx
get path/to/file.xxx
send path/to/file.xxx
whatever other/cmds/you/want.xxx
quit / bye
#
good luck. no don't forget to post how to use 'at'!
