"File-sharing between Windows and Sun's OpenSolaris Unix platform is being bolstered through two projects at Sun. The OpenSolaris project: CIFS Server features server software source code that implements the CIFS protocol also known as Server Message Block, the standard for Windows file-sharing services, Sun said. The internal CIFS server enables Microsoft users to store and retrieve files on an OpenSolaris system, Sun said. This project and a related effort, CIFS client, improve the usefulness of OpenSolaris in data environments that serve NFS and CIFS clients, Sun said. Sun recently donated server source code that implements CIFS to the OpenSolaris Project."
