I ran a best practices scan of my SBS 2008 box, and it said Rollup 4 was not installed. I am actually trying to install Rollup 5. Updates were last installed on the SBS 2008 machine about 2 weeks ago, so I'm versy surprised it didn't include Rollup 5 (let alone Rollup 4).
I've checked the server again using Windows Update, and it did find several important updates, none of which are Rollup 5.
Am I missing something? How do I get Rollup 5?
