I’ve been waiting a bit too long to update here and missed a few things…

First, Joseph Davies (aka “The Cable Guy” on Technet) has released the entire TCP/IP Fundamentals for Microsoft Windows in PDF format.

More to come later today or early tomorrow…

Spring 2007 Cable Guy Articles Rollup

jeffreycentex — Wed, 20 Jun 2007 02:52:55 +0000

In my absence, I have missed the past few Cable Guy articles over at Technet:

June 2007 – The Secure Socket Tunneling Protocol

This article from TechNet Magazine describes how the Secure Socket Tunneling Protocol (SSTP) uses the HyperText Transfer Protocol (HTTP) over secure sockets layer (SSL) for remote access virtual private network (VPN) connections across network address translators (NATs), firewalls, and proxy servers.

May 2007 – EAPHost in Windows

This article from TechNet Magazine describes the new architecture in Windows Vista and Windows Server 2008 (now in beta testing) to support Extensible Authentication Protocol (EAP) supplicants and authentication methods.

April 2007 – Wireless Group Policy Settings for Windows Vista

This article from TechNet Magazine describes the enhanced wireless Group Policy settings that are supported by wireless clients running Windows Vista or Windows Server 2008.

I plan on testing out the SSTP (or SSL VPN) capability in Longhorn Server for a few people at the office who can’t use PPTP or L2TP VPN technologies.

Book: TCP/IP Fundamentals for Microsoft Windows

jeffreycentex — Fri, 26 May 2006 06:18:45 +0000

Joseph Davies (of the Windows Server Networking team and also known as the Cable Guy) has recently released a new online book entitled TCP/IP Fundamentals for Microsoft Windows that is available on Technet.

From Joseph’s posting on the server networking newsgroup:

This online book is a structured, introductory approach to the basic
concepts and principles of the Transmission Control Protocol/Internet
Protocol (TCP/IP) protocol suite, how the most important protocols function,
and their basic configuration in the Microsoft® Windows Server® 2003 and
Windows® XP operating systems.

This online book is available for free and provides a central location for
an existing or aspiring Windows network administrator to get a comprehensive
view of TCP/IP protocols and services in Windows XP and Windows Server 2003.
Unlike many other introductory TCP/IP book, this book provides an integrated
discussion of both Internet Protocol version 4 (IPv4) and Internet Protocol
version 6 (IPv6).

Cable Guy: Changes to IPv6 in Windows Vista and Windows Server Longhorn

jeffreycentex — Fri, 30 Sep 2005 08:50:14 +0000

There’s a new Cable Guy article entitled “Changes to IPv6 in Windows Vista and Windows Server Longhorn” that was posted yesterday…

I’ll learn a bit more about this tomorrow at the Network Drill-Down day at the MVP Summit… So hopefully I can post a bit more later this weekend if I am able to due to NDA.

August 2005 Cable Guy: WPA2 Encryption Details

jeffreycentex — Tue, 09 Aug 2005 01:21:04 +0000

The August 2005 edition of The Cable Guy involves the new encryption standards that will be included in the WPA (WiFi Protected Access) implementations. This article is good if you want specific details on the Encryption and Integrity aspects of WPA2.

Cable Guy: Network Access Protection Overview

jeffreycentex — Sun, 10 Jul 2005 05:45:38 +0000

This month’s Cable Guy article is an overview of NAP (Network Access Protection), which stands for Network Access Protection. NAP is set to be included “server”-wise in the Longhorn Server release (parts of it was supposed to be in R2, but they were dropped a few months back), and client wise in Windows XP and Longhorn.

NAP will allow you to quarantine computers (either local OR remote) that don’t meet a security profile (i.e., patch level, virus definitions, etc) from your secured network. This should be MUCH easier to set up than the current Quarantining features contained in Windows 2003 and refined in R2.

As a manager of a network in a mid-sized business, this feature has been long sought after. I was kinda disappointed when the preliminary NAP support was removed from R2, thus forcing a two year delay in deployment.

For a good overview, check out the article.

Cable Guy: March and April Updates

jeffreycentex — Sun, 24 Apr 2005 07:17:43 +0000

In my (recurring) downtime, I missed the past two magnificient Cable Guy articles.

In March: Troubleshooting IPV6

This article describes the techniques and tools that you can use to help identify a problem at successive layers of the Transmission Control Protocol/Internet Protocol (TCP/IP) protocol stack that is using an Internet Protocol version 6 (IPv6) Internet layer in Microsoft® Windows® XP with Service Pack 1 (SP1), Windows XP with Service Pack 2 (SP2), or Windows Server 2003.

In April: Windows XP and Windows Server 2003 Behavior When Connected to Both Wired and Wireless Networks

This article describes how computers running Microsoft® Windows® XP or Windows Server™ 2003 behave when they have simultaneous connectivity to both wired and wireless networks. This article also describes workarounds for ensuring either that only one network adapter is active at any one time, or that the majority of the network traffic flows over the desired network adapter.

The Cable Guy: Improvements in Win2K3 SP1

jeffreycentex — Tue, 07 Dec 2004 07:46:44 +0000

The December edition of The Cable Guy is out.. This issue is packed with information concerning networking and security improvements that are contained in Windows 2003 Server Service Pack 1. I have been playing around with this for some time as this is the never-ending beta, but I haven’t mentioned much due to the fact that it is still in Beta… However, the key factors for me are the improvement in network quarantining (but it still isn’t NAP (Network Access Protection)) and the TCP/IP hardening…

Well, go ahead and check it out… Click here

Missed Cable Guy Articles

jeffreycentex — Mon, 01 Nov 2004 22:50:08 +0000

In my absence, I missed posting about a few of the newer Cable Guy articles. In case you haven’t seen them, here is a list. The October one is particularly relevant as NAT is the cause for many of our SOHO networking woes…

October 2004 – Problems with Using Network Address Translators

Learn about the pitfalls of network address translators (NATs) when using multiparty applications, peer-to-peer applications, and Internet Protocol security (IPSec) NAT-Traversal (NAT-T).

September 2004 – Introduction to Mobile IPv6

Request for Comments (RFC) 3775 defines Mobile Internet Protocol version 6 (IPv6), which allows an IPv6 node to remain reachable regardless of its location on an IPv6 network and whether the nodes with which the Mobile IPv6 node is communicating also support Mobile IPv6.

August 2004 – Wireless LAN Enhancements in Windows XP Service Pack 2
