Microsoft: Start Preparing for SMB1's Demise
Windows Server still recognizes the venerable protocol, but support is dwindling, Microsoft warns.Server Message Block version 1 (SMB1) is being phased out, and organizations that are still relying on the protocol may have a tough time implementing upcoming Windows technologies, cautions Microsoft. SMB is a network file sharing protocol that enables shared access to remote servers and their resources, such as files. Unable to handle large data sizes well along with new features added to Microsoft's NTFS file system, the company introduced SMB2 in the Windows Server 2008 operating system. Now, SMB1's days are numbered, but it should come as no surprise to IT watchers following the evolution of Windows Server, according to Jose Barreto, a principal program manager on Microsoft's File Server and Clustering team. "We already added SMB1 to the Windows Server 2012 R2 deprecation list in June 2013," he said in a company blog post. "That does not mean it's fully removed, but that the feature is 'planned for potential removal in subsequent releases.'" One reason to start preparing for SMB1's demise is Windows Server 2003's impending support deadline. "The last supported Windows operating system that can only negotiate SMB1 is Windows Server 2003," he said. "All other currently supported Windows operating systems (client and server) are able to negotiate SMB2 or higher."
Microsoft is pulling support on the 12-year-old server operating system (OS) on July 14. While many organizations have already kicked off the migration process, a recent Spiceworks survey discovered that some holdouts may be facing security, software compatibility and compliance risks when the deadline expires.
