For Windows Server 2008 SP2, Microsoft will include Backwards compatibility with Terminal Services licensing keys, improved manageability features with DFS/FRS console, and Storage Resource Manager, print server and spooler performance improvements for printers in Windows Vista and Server 2008 and improved error reporting in DFSR to help identify incorrectly configured deployments which lead to failed replication.
