Windows 2000 Will Enable Microsoft to Continue to Dominate Client and Server Operating Environments, IDC Says

FRAMINGHAM, MASS., FEBRUARY 16, 2000 — The launch of Windows 2000 will enable Microsoft to continue to dominate the client operating environment market and come to dominate the server operating environment market. IDC believes Windows 2000 will ultimately see widespread use, but the acceptance of this new software will be slowed by organizational concerns about the stability of Windows 2000. This indicates that organizations will begin to use Windows 2000 six months to a year after its release by Microsoft, scheduled for later this week.

"On the client side, by the end of IDC's forecast period (2004), Windows 2000 Professional is expected to maintain its position as the number-two client operating environment behind its cousin Windows 98," said Dan Kusnetzky, program director, Operating Environments and Serverware, IDC. "On the server side, during the same time frame, Windows NT/2000 is expected to have moved from being the leading server operating environment to being the dominant server operating environment."

Discussing this announcement can be quite confusing because Windows 2000 is merely a new version of Windows NT even though Microsoft is positioning the product as something quite different. Confusion can also arise due to the fact that both the client version (Windows 2000 Professional) and the server versions (Windows 2000 Server, Windows 2000 Advanced Server, and in the future, Windows 2000 Datacenter Server) share many features.

IDC recently published two bulletins on the launch of Windows 2000 and its effects on the operating environment market. Microsoft Launches Windows 2000 Professional (IDC #B21601) and Microsoft Launches Windows 2000 Server (IDC #B21663) discuss when and if Windows 2000 will be a successful product and how it will affect both the client and server operating environment markets for the next several years. These two bulletins also include Windows 2000 product features, pricing, support, and expected adoption rates.

Additionally, IDC published the Operating System Functionality Matrix (IDC #B21229). This report includes feature/function comparisons for a wide variety of server operating environments, including the new Windows 2000 Standard and Advanced Server products, the forthcoming Windows 2000 Data Center product, many vendors' versions of Unix, two releases of Linux, Novell NetWare, and several host server operating environments, including IBM's OS/390. This version of the IDC Operating System Functionality matrix can be compared with previous years' versions to track vendors' progress in enhancing their products. Importantly, it provides a "level playing field" that allows readers to compare operating environments across the board, providing a depth of data not available in vendor press releases and technical spec sheets.
