ArGoSoft FTP Server .NET (64-Bit)

From ArGo Software Design:

ArGoSoft FTP Server .NET (64-Bit) is a FTP server with unique advanced features, such as passive mode, resuming file transfers, windows shortcuts, file archiving directly on the server, and DOS shell. Server has a "smart guessing" system, which attempts to track down suspicious activity and blacklist IP addresses which seem to be the originators of such activity. It is called as Automatic Lockout system. It protects you from "brute force" password guessing attempts and other connections which generate errors.
