I know under XP you can install IIS and run an FTP server for that. Try poking around in the Add/Remove programs control panel under Add/Remove Windows components. There may be something of interest there.
Yes...it's a componnent of IIS which can be installed from Add/Remove Programs-->Windows Componnents. Once you install it when you right click My Computer and go to Manage -- one of the options should be FTP...you can manage security there. Make sure you don't install all the other stuff from IIS unless you actually need it. Good luck.
