All passwords used by Windows networking services are encrypted. However, the Ftp, and Rexec connectivity tools all rely on cleartext password authentication by the remote computer. Cleartext passwords are not encrypted before being sent over the network. This enables another user equipped with a network analyzer on the same network to steal a user's remote account password. For this reason, choose different passwords from those used for Windows 2000–based computers or domains when connecting to non-Microsoft remote computers with the Ftp, Rexec, or Telnet tools. Note that the protocols themselves prohibit encryption; cleartext passwords are not a standard that Microsoft encourages.
