I have a situation that a Windows 2000 loaded pc should login to
internet everyday at a certain time and ftp a certain file from a
website and disconnect the internet connection. I have machines with
Windows 2000 profesional and another machine with Windows 2000 server
and I can use anyone for the above case.

Please help me on how to automate the above said task (connect to
internet - download a file - disconnect internet) so that it would
work everyday without any manual intervention.

Thanks in advance.
