AD environment values

I have two values that I would like to make available for all computers
connected to a domain: a URL and a ****t number.  I am trying to avoid
running a script (I will if I need to), but isn't there a way to create a
value in AD so that it is available to every machine connecting to the
domain?  I need that value available during logon, before any user profile
info is available (as the user hasn't logged on yet).
