I´ll be there !!!!
Be prepared for my hard questions ;-)
Bye from Spain.
Will this be archived for those of us that can't make it in person?
Absolutely! If you missed the presentation or want to watch it again, it'll be available for on-demand downloading in the next few days. The transcript will be posted in a few weeks. Both of these are at: http://support.microsoft.com/?id=839816
Can anyone fill me in on why I must have NNTP installed and enabled in order to apply SP1?
NNTP being installed is a prerequisite for any run of Exchange 2003 setup/update. This is because the NNTP core functionality actually ships with Windows and Exchange merely utilizes and adds to it. In order to register the Exchange NNTP updates for SP1, the core functionality must also be installed. This is the same reasoning that also requires Windows SMTP be installed.
Hope it helps!
