A. IIS 5.0, the version that ships with Windows 2000 has a number of enhancements. One of which is the FTP resume mode which if a download is halted and you disconnect, upon reconnecting you will be asked if you wish to resume the download. This is very useful for downloads of large files.

This functionality does not work using the command level FTP provided with Windows NT 4.0, however software packages such as WS_FTP Pro from www.ipswitch.com allow this.

FTP Resume is turned on by default in Windows 2000 but as far as I know it is not possible in IIS 4.0 or lower.
