Can Wincvs use rsh (:server:) connection method?

[Steve Rabin]

Is it possible to convince Wincvs to use the rsh (:server:) connection method
rather than the pserver method described in the Wincvs docs?  I don't want to
have to mess with sysadmin to change the inetd.  I am willing to limit use
to trusted machines listed in rhosts.  When I try setting the method to server
I keep getting the message:
Set the password authentication first in the preferences !

But I can't seem to figure out what to click on to tell Wincvs what password 
to use with this rsh method.

Thanks and Best Regards,

Steve
