The content is based on years of experience asking and answering questions regarding Samba Technical and jCIFS Developer mailing list, and spent many hours pouring over the documentation is clear, trace packages, and source code. The goal is to help the reader, no matter what platform they work, develop an understanding of the protocol, and acts as a guide for more detailed specifications and technical reference available.The large installed base of Windows systems have given the status of de facto standard CIFS protocol (system Microsoft filesharing). Unfortunately, implementation documentation and detailed protocol specification scarce, incomplete, or inconsistent.This is a good problem for network administrators and third-party CIFS implementors and the need for this book is clear.
