Wham! Good answer! It works!

Actually I viewed the "unused_by_nt/2000/xp" string as ugly and replaced 
it with the traditional "*" instead. But you're right, if you put 
anything in there it gives me a Permission denied for "rsh <machine> 
<command>". Looks like some security checking got tightened up.

This does lead to a question as I believe some other services (ssh? 
exim? I forget) require that you put an actual passwd in /etc/passwd. 
They also described how to generate the crypt string. I've done this on 
my home machine so I copied that encrypted string to my work machine and 
I still get permission denied. Sounds like it's still a problem but at 
least I have a workaround for work. Thanks.
