Here are four presentations I've done for BNUG over the past year or so that I've been asked to put online. Please remember that I authored them - feel free to use the material here, but please attribute where appropriate. They are, as follows:
Introduction to Windows NT - Basic Concepts
From BNUG Windows NT seminar, Fall 1998
From BNUG Intermediate TCP/IP seminar, July 2000
From BNUG General Meeting, January 1999
From BNUG General Meeting, May 1999
Building a Homenet - version 2.0
From BNUG General Meeting, July 2000

Our vendor presentation in July of 1999 was by the folks at Packeteer - who have a fascinating product that (essentially) allows you to take advantage of TCP flow control to throttle and prioritize your IP bandwidth. I've archived their presentation at this link (warning - it's a 2 meg .zip file)
I also have a copy of Nortel's presentation from the June 2000 meeting on the subject of IP Telephony.
Also mirrored is Nat Kennedy's presentation from the 7/15/2K TCP/IP seminar at this link.
