Windows Vista with SP1 or later and Windows Server 2008 have several networking enhancements that affect networking and NDF in general including Support for Server Message Block SMB version 2 SMB is the file sharing protocol used by Windows operating systems. Windows Vista and Windows Server 2008 support SMB version 2 which enhances the performance of the original SMB protocol. Windows Vista with SP1 or later and Windows Server 2008 support the SMB Helper Class as part of the Network Diagnostics Framework NDF . This helper class provides diagnostics information users will find useful when they are having problems connecting to file shares. Specifically this helper class can help diagnose failures including when a user is trying to access a server that does not exist when a user is trying to access a nonexisting share on existing server and when a user misspells a share name and there is a similarly named share available. Note When working with Windows Vista SP1 or later and Windows Server 2008 file access and remote copy performance is increased significantly. SMB v2 offers significant file transfer improvements as do improved file transfer algorithms. Additionally network share thumbnails are cached for all users allowing faster display of thumbnails when working with network shares. Implementation of extensions to network awareness Improvements in network selection algorithms allow a computer connected to one or more networks via two or more interfaces regardless of whether they are wired or wireless to select the route with the best performance for a particular data transfer. As part of the best route selection Windows chooses the best interface either wired or wireless for the transfer and this improves the selection of wireless over wired networks when both interfaces are present. 18 Chapter 1 Introducing Windows Server 2008 Chapter 1 Changes to network management policies Network
