Susan, I know that the free/busy information automatically publishes with Outlook 2002 clients.  But I am saying that it does not automatically publish with Outlook 2003 clients.  We have two installations with this exact configuration (Exchange 2000 running on a SBS 2k server) and neither one publishes free/busy info for Outlook 2003 clients.

And yes, I have seen driver updates show up in critical updates on occasion.  I was wondering why this happens.
