Beginning July 1, the Microsoft Active Directory service maintained at the Data Center began operating a production forest using Windows 2003 software. The forest is accessed by campus departments when sharing computer resources and calendars using Microsoft Outlook and Exchange. Current production users have developed a migration plan to move from the Windows 2000 forest to the Windows 2003 forest. The Windows 2000 forest will be discontinued after the migration is complete, which is expected in the Fall. Information at http://windows.ucdavis.edu is being updated to reflect these changes.
