In addition to my fortnightly visit to the pages of this august journal, I also supply Network World Fusion with semiweekly newsletters in three different areas. Two of those deal with\u00a0NetWare\u00a0and\u00a0Windows\u00a0servers. In both I'm right in the midst of a series of issues previewing the new features and functionality of the upcoming server releases from\u00a0Novell\u00a0and\u00a0Microsoft.Some pundits have alleged that NetWare 6.5 and Windows Server 2003 (aka Windows 6.0) are only minimal improvements over their predecessors, NetWare 6.0 and Windows 2000. If you look at the core operating systems, that might be close to being true (if the lighting is low, and you squint) but that's not the important thing about these upcoming releases.Provo and Redmond face the same problem - users who are quite happy to continue using Version 4 of their server operating systems. Heck, Novell still has a significant number of users running Version 3 of NetWare, but it appears there's absolutely nothing else Novell Vice Chairman Chris Stone and his crew can do to get those 15- to 20-year-old systems uprooted. So they no longer try.But both Stone and Microsoft CEO Steve Ballmer know that the fiscal well-being of their companies rests with enticing people to trade up from NetWare 4.X and 5.X to NetWare 6.5, and from NT 4 and Windows 2000 to Windows Server 2003. Both, it seems, have learned a lesson from the automakers.Gas-mileage requirements have pretty much dictated the aerodynamic design of today's automobiles. The radical designs of the late 1950s and early '60s might never be seen again. So automakers compete on interior features and add-ons. And that's where the new network server operating systems also will compete. It's less about competing with each other, though, and only partially about competing with\u00a0Linux\u00a0and\u00a0Unix\u00a0systems. The real battle is to get those older operating systems upgraded and updated. After all, the network managers running those older systems already believe they have made the right choice of vendor, so half the battle is won.Both Novell and Microsoft are adding large amounts of utilities and functionality to their servers, including major features to overcome traditional weak areas - application services for NetWare and security services for Windows. If you are running older NetWare or Windows be sure to check out all the new goodies on offered in the new systems shipping in the next few months.Tip of the weekJust in case you haven't bothered to subscribe to the great newsletters offered on Network World Fusion, head over to www.nwwsubscribe.com\/foc15\/ and sign up now.
