|| More Centralized Management: Provides centralized management tools for file and print functions Reduced Remote Administration: Minimizes local administration and local back up Better WAN Efficiencies: Enables faster data replication over wide area networks Greater User Efficiency: Fewer user passwords, for both internal and partner-hosted web applications, through extranet Single Sign-On and identity federation Enhanced IT Efficiency: Centralized administration of extranet application access, fewer password resets, and the ability to delegate user management to trusted partners Better Security: Automated "shut off" of extranet access based on disabling a user's Active Directory account Better Regulatory Compliance: Log user access to partner applications in external security domains Improved Interoperability With Heterogeneous Systems: Cross-platform Web Single Sign-On and identity federation using Web Services interoperability specifications and tools to manage and dynamically update user accounts and passwords across Windows and UNIX systems using Network Information Service (NIS). Also performs automatic synchronization of passwords between Windows and UNIX operating systems. Better Storage Utilization: Provides storage utilization information through detailed storage reports Better Quota Management: Monitors and controls disk space usage with directory quotas Better File Screening: Limits types of files allowed on servers with file screening Simpler SAN Configuration: Easily configures and provisions storage area networks (SANs) Better Performing Web Platform: Latest 64-bit and .NET technologies double the Web performance Better Virtualization Value: Windows Server 2003 R2 Enterprise Edition provides better value in server virtualization. Licensing policy changes now allow customers to run up to 4 virtual instances of Windows Server 2003 R2 Enterprise Edition on one licensed physical server or hardware partition. Enable Cross Platform Management: UNIX administrators can manage both UNIX and Windows systems using many tools, utilities and scripts that you are using today with the Utilities and SDK Web Download, which includes shells and SVR-5 utilities. Windows administrators can use familiar Windows commands to manage UNIX systems, users, permissions and passwords. Integrate UNIX Applications: The Sub-system for UNIX-based Applications (SUA), is a source-compatibility subsystem for compiling and running custom UNIX-based applications on Windows Server 2003 R2. SUA allows for some parts of a UNIX application to be run on Windows, for instance building a Windows-based Graphical User Interface (GUI) for an existing UNIX-based application. Migrate UNIX Applications: SUA enables the phased migration of UNIX-based applications by allowing most custom applications to be re-compiled and run natively on Windows. Applications can be converted or re-written one component at a time, without significant end-user downtime or extensive cut-over times.
