Bless her cotton socks, good old SMS2003 moves out of mainstream support at the end of January, and it's site on the microsoft domain has had a refresh and has now become more of a portal to assist in migrating from SMS2003 to ConfigMgr. This doesn't mean it is no longer supported by MS, just means it moves from mainstream support to extended support($$$).
Jeff Wettlaufer recently blogged about this:
This week SMS 2003 moves out of mainstream support, and enters what is called Extended Support. This is a natural transition for every Microsoft product. Information about the SMS 2003 product lifecycle can be found here.
SMS 2003 has been an incredibly popular product, and has been considered the most widely deployed management tool in the world. Many customers who at some time were running a version of SMS have since migrated to Configuration Manager 2007, but we recognize this is not the case for everyone.
The industry has moved at a pace unparalleled by most. Technology has accelerated in capability, adoption, depth, breadth, and complexity. From a management perspective, the landscape configuration management technology embraces has grown from basic inventory and software distribution to new areas like OS deployment, Virtualization, Asset/ Performance and Workflow management, data protection, NAP and model based configuration management. In addition to capabilities, new working styles, scenarios, users (Gen ‘Y’) and security models have become daily routine for Administrators.
The management landscape has changed, there is no debating it.
System Center Configuration Manager 2007 is in the 4th release since SMS 2003. With a 5th (R3) entering beta soon, and with the mainstream support cycle ending for SMS 2003, we wanted to collect as much assistance as possible
