Technical documentation for Windows Server Protocols and authentication 101

Yesterday I rediscovered a great resource about Windows Server protocols when I was debugging SMB2 and Kerberos V5 traffic between Windows 7 client, Netapp filer and DC on Windows Server 2008 R2.

I found out a page on MSDN that contains the technical documents for the Windows Server Protocols (WSPP) documentation set. Especially [MS-SPNG]: Simple and Protected GSS-API Negotiation Mechanism (SPNEGO) Extension, [MS-KILE]: Kerberos Protocol Extensions and [MS-SMB2]: Server Message Block (SMB) Version 2 Protocol Specification

I also found helpful blog post on Microsoft Open Specifications Support Team Blog explaining authentication in Windows.
