The new server operating system, previously known as Windows .NET Server, is one of the cornerstones of Microsoft's .NET strategy -- together with Microsoft's Office 2003 and Visual Studio .NET 2003 products -- and paves the way for XML Web services and tightly integrated collaborative technologies.
The product takes more of an all-in-one approach than previous versions of the server operating system, which tended to be more specialized for particular functions. The new software will handle file and print serving, Web serving and Web application serving, mail serving, directory services, and streaming media serving. It can also be used as a terminal server, remote access/virtual private network (VPN) server, Domain Name System (DNS) server, Dynamic Host Configuration Protocol (DHCP) server and for Windows Internet Naming Service (WINS).

Another edition, Windows Small Business Server 2003, is planned for release in the summer.
Microsoft aimed to make this version of its server operating system the most stable it has ever shipped, and it includes a "No Reboot" initiative, according to Laura DiDio, analyst with The Yankee Group. DiDio said the operating system is an order of magnitude more reliable than Windows 2000 Server Service Pack 2. She added that Windows Server 2000 itself was far more reliable and scalable than Windows NT Server 4.0, with about 60 percent fewer reboots than that operating system.
The product has been years in the coming. Initially, the company scheduled it for release in the second half of 2001, but it delayed the launch three times. According to Laura DiDio, analyst with The Yankee Group, the delays were to fulfill Microsoft's Trustworthy Computing Initiative, announced in January 2001 in an effort to combat the company's reputation for making products that were easy targets for hackers. By July 2002, the company had spent more than $100 million to go through every line of Windows code in an effort to make it more secure.
"They will ship no product that is not secure," said DiDio, who added that the Trustworthy Computing Initiative is very much in evidence at Microsoft. "That is the main reason that they attributed to the 16 to 18 month delay in shipping Windows Server 2003."
But while customers have had a long wait for Windows Server 2003, whether they will upgrade to the new operating system remains up in the air according to DiDio.
A recently completed Yankee Group Survey, conducted with Sunbelt Software, found that 34 percent of businesses plan to make the upgrade, but 15 percent have decided to avoid the new operating system and 50 percent have not yet decided. The survey questioned 1,000 IT managers and chief technology officers. DiDio said 50 percent of the respondents were in the small and medium business market (SMB), with between one and 1,000 end users, and 15 percent came from very large enterprises.
DiDio said that constrained IT budgets have led to three and a half to four, five or even six year upgrade cycles in many businesses, and many IT decision makers may decide to try to wait Microsoft out and upgrade with the next version of Windows Server. That product is code-named Blackcomb, and is expected in 2005 or 2006.
"Microsoft's biggest competitor in this space right now is itself," she said.
Of those who do plan to migrate, 7 percent said they will make the switch as soon as the software ships, 11 percent said within three to six months, 5 percent said within six to nine months, and 14 percent said within the next 12 months. A further 63 percent said they have no definitive plans to migrate.
