LOS ANGELES�Bob Muglia, Microsoft Corp.'s senior vice president for Windows Server, on Thursday shed some light on the upcoming Windows Server 2003 R2 release during his keynote address at the Professional Developers Conference here. R2, which is due later this year, would bring features such as Services for Unix, the WS-Management standard, along with the next generation of the management console, MMC 3.0. "Closing the loop between developers and operational systems still has a long way to go, but delivering MMC 3.0 is the first deliverable in that regard," Muglia said. "With R2, we'll also deliver the first version of Active Directory Federation Services (ADFS) to make it easier for developers to build federated Web applications. In the Windows Vista timeframe, we will deliver WinFX and the 'InfoCard' user experience," he said. "With Windows Server 'Longhorn,' we will begin to align the existing technologies around a common architecture, policy, developer model and management experience. Later in the Longhorn wave, Microsoft will add new capabilities to Active Directory, such as the Security Token Service, to simplify identity and access in a service-oriented world.
