windows 2000 & windows 2003 network architecture

[hubabuba]

Hi!

I have found the description windows 2000 network archticture in terms of layers:

Basic Netork Services Layer

Interprocess Communication Layer

Network Application Programming Interface Layer

Transport Driver Interface Layer

Network Protocol Layer

I also need to find the same for windows 2003, but I looked and could not find anything like this, not even Microsofts web site has it (it did for windows 2000 though). Does anyone know where to find this info?
