Fingerprint export and the match object definition do not really need to use hexadecimal notation here (the actual signature is ASCII text in this case). Hexadecimal is only required for binary signatures.

Other examples for Windows Server 2003 or any other Windows version might be easily obtained using the described method.

Linux/UNIX administrators need to customize the default environment variable to take advantage of this signature based defense, as the default prompt is typically not sufficiently specific or unique to be used as described above.
