SSH Secure Services on Windows 2K/XP?

jstockdale asks: "Lately I've been working on the security of the few Windows boxes I administer, specifically XP and 2000 stations. I havn't had much of a problem finding decent solutions for file/email/disk encryption (besides the fact that PGP is no longer selling their products), or for smartcard or smartcard+biometric solutions (besides the limitations on key size (2048-bit RSA maximum) and flexability). However when it comes to SSH services for remote administration, windows filesharing, and SFTP for file transfers I have hit a dead end. I have looked into SSH but their SSH for Windows Servers only runs on 2000, and costs $565. I ask what solutions have /.er's found in the realm of ssh network encryption, and also in integrating all these components simply and effectively."
