I've had a lot of questions about the Vista update that's coming to fix client deployment to work for Vista clients. Everyone by now has seen the How to run Vista RC1 on SBS. This post applies to Vista RTM (The final release bits) as well.
Unfortunately, the Vista Update for SBS 2003 (code named "RipCurl") won't be ready until Vista ships to consumer customers. Yes, I'm aware that Vista RTM is available to MSDN and other package subscribers today. In addition, volume license customers (enterprises, etc) will be able to get it within the week (November 30th is the date I've heard rumors of, no holding me to it though!). And In Jan/Feb of next year is when Vista and the Vista Update for SBS 2003 will be available to all customers.
I appologize for those SUPER early adopters (hey, because you're exactly like myself!).
