The protocol is available. Ftp is a service. Once started, it will be created in a sub-environment where ftp commands can be used.
The sub-environment returns to the Windows 2000 command prompt. When the ftp sub-environment is running, it is represented by an ftp command prompt.
Ftp [-v] [-n] [-I] [-d] [-g] [-s: filename] [-a] [-w: windowsize] [computer]
