recommended reading for winsock?

just for a learning exercise, i am currently writing a dinky little server/client that kinda mimmics icq/aim. now, that i'm kinda into it, i need more info on winsock. are there any good books about winsock? i heard windows sockets network programming is really good, but its old. are there any good ones that cover winsock2? topics i am looking for in the book are:
1) winsock2
2) multithreading issues when dealing with sockets
3) the MFC wrapper classes (CAsyncSocket and CSocket)
4) lots of good example code and programs

thank you!
