Windows 2003 compatibility issues upset some IT pros

Computerworld - Some IT managers aren't happy. Others are more understanding. But all of those planning to upgrade to Windows Server 2003 will find that many older versions of Microsoft Corp.'s most popular server applications won't run on the new operating system.

Only SQL Server 2000 with Service Pack 3 can be installed on Windows Server 2003. Users running SQL Server 6.5 or 7.0 will have to upgrade or wait for the SQL release code-named Yukon, which will soon go into beta testing.

Exchange Server users have one choice. The only version that can be installed on the new operating system is Exchange 2003, and it's not due until summer.

"I think Microsoft owes it to their customers to ensure backwards compatibility and interoperability for at least five years," said Derek Gee, vice president and director of system architecture and integration at Ameriquest Mortgage Co. in Orange, Calif.

"Another reason Microsoft should support some of their older versions is to maintain customer loyalty," said Steve Sommer, CIO at Hughes, Hubbard & Reed LLP in New York. "There are some big customers that cannot afford to upgrade right now."

Many users are sympathetic to Microsoft's claims that extensive security, Web server and Active Directory improvements affect not only the operating system but also any applications that rely on it. They said they understand why some older applications won't be supported on Windows Server 2003.

"If it's really a major upgrade, then Microsoft can't be expected to make substantial improvements to the product while at the same time bringing along all its old baggage," said Rich Eber, development service director at Hawaiian Electric Co. in Honolulu.

But if users find that the core Windows server operating system hasn't changed internally as much as Microsoft has portrayed, "there should be a backlash against this lack of support," Eber said.

Neville Teagarden, CIO at Navigant International Inc. in Englewood, Colo., said security has spurred his company to invest time during the past year to get the latest versions of Microsoft software. "My CIO colleagues should be asking themselves whether they can afford the security risks of using older versions of Microsoft products," he said.

Those users who have lagged on upgrades, however, may not be pleased to see that Microsoft won't be supporting older versions of its software on the latest operating system.

"Expecting companies to upgrade everything in their infrastructure to get the features from a single product, in this case Windows 2003, is unrealistic," said Dave Curran, manager of IT at CE Franklin Ltd. in Calgary, Alberta. "This smells of a pure money grab by Microsoft."
