MCPP Protocol Documentation

The Microsoft Communications Protocol Program (MCPP) technical documentation set provides specifications for protocols that are implemented and used in Windows client operating systems (specifically Microsoft Windows 2000 Professional and successors up to and including Windows Vista) to interoperate or communicate natively with Windows Server operating systems (specifically Windows NT 3.1 up to and including Windows Server 2008).

These MCPP protocols are published and freely available on MSDN.

The documentation set includes a set of companion overview and reference documents that supplement the technical specifications with conceptual background, overviews of inter-protocol relationships and interactions, and technical reference information, such as common data types and error codes.

Microsoft will publish documentation for new or modified MCPP protocols as follows:

• If there is a beta release of updates to or successor versions of Windows client and Windows Server operating systems that contain the modified or new MCPP protocol, the updated documentation will be published no later than the date on which the first public beta testing version of the relevant update or successor version containing the applicable MCPP protocol is made available by Microsoft through an MSDN subscription offering or of which 150,000 or more copies are distributed. This beta documentation will be updated to correspond to the commercially released version of the applicable update or successor Windows products no later than 15 days before the commercial release of the relevant update or successor Windows products.
• If there is no beta release, the updated documentation will be published no later than 15 days before commercial release of the relevant update or successor Windows products.
