I'm running an OS X Server 10.6 guest on a Mac Pro running OS X 10.6.4. The guest OS runs fine, but won't update via the normal "Software Update..." function - it reports no updates available, even though there have been numerous security and OS updates since the disc I used to install it was released. Is there some trick I need to use to get it to find the appropriate updates? After the initial install it did update iTunes, iLife Support, AirPort Base Station and the Remote Desktop Client, but it doesn't find any security updates or the update to 10.6.4.
