I've been watching this thread, and finally thought I'd point something

Windows machines can query (and set) the time from each other.

On a Windows machine, from the command line, type 'net time /?'

For example on our local network, I can do:

net time \\public /set /yes

And my machine is reset to the value of the clock on \\public

What we do here at work is we purchased -one- of the NTP clients, and run
it on \\public.  Then, everyone's Windows network login has a login script
associated with it that has the line I listed above in it.

Hence, every time anyone logs into a machine here at work, the clock is
synchronized with \\public, which has been synchronized with a Naval

I understand the principle of wanting to make the d.net clients do
something 'useful' (proving encryption isn't secure isn't 'useful'?), but
this particular task seems like you could do it easily enough without the
extra effort. :)
