Ed Liberman reporting live from the 2012 TEC – The Experts Conference in San Diego, CA. Learn about a couple of interesting sessions from the conference on automating user profile migration and what’s new in Active Directory in Windows Server 2012.
The new MCSE certifications have spawned a number of questions and concerns. In this article we’ll examine what is known about the new MCSE certs and what there still seems to be some questions about. MCT Ed Liberman will also offer his advice on how to make sense of it all.
The popular MCSE certification is back — reinvented. Microsoft is launching the new lineup of MCSA, MCSE, MCSD and MCSM certification tracks which will be tied to all new Microsoft technologies. Learn about the new MCSE and how the new certification tracks break down.

In this video presentation Ed Liberman, a 20 year IT veteran and Microsoft Certified Trainer, will provide you with a practical understanding of the OSI model and the TCP/IP protocol suite — all in under 1 hour.
Learn how to convert your existing VMware virtual machines to Hyper-V using System Center Virtual Machine Manager 2008 R2. In this video, instructor Ed Liberman, walks you through the process step-by-step.
In this video we take a closer look at a new tool included in Server 2008 R2 and Windows 7, called Djoin.exe, which allows clients to be joined to a domain without any network connectivity. Let me show you how Active Directory Offline Domain Join works.
The new Active Directory Best Practices Analyzer (BPA) in Server 2008 R2 is a tool that is now capable of examining Active Directory Domain Services (AD DS) and can help administrators reduce best practice violations by scanning AD DS and reporting best practice violations.
The Server 2008 R2 Active Directory Administrative Center is a new tool which can enhance the way administrators manage Active Directory objects allowing you to easily create and manage user accounts, groups, computer accounts, and Organizational Units (OUs).
I just finished giving my presentation on my three favorite TechEd 2010 presentations at our local Chicago Windows User Group meeting. Below are the slides from the presentation which include most of what I talked about including the links to TechEd resources that I thought would be valuable. What I focused on was my three [...]
This network devices review concludes our CompTIA Network+ training series. These videos help to describe various network devices, functions, and appropriate times to use them.
In this video, I’ll go over two networking devices that you’ll need to know about before taking your CompTIA Network+ certification exam. You’ll learn about the differences between load balancers and bandwidth shapers. Load balancers are generally used when there is more than one form of communication available. They help to divide communication evenly between [...]
Learn what a media converter is, how it works and how it differs from Channel Service Unit/Data Service Unit (CSU/DSU).
In this CompTIA Network+ training video, I’ll go over what Channel Service Units (CSUs) and Data Service Units (DSUs) are, what they do, and why they are used. A CSU/DSU is a hardware device that converts data frames used on a LAN into data frames used on a WAN. Typically, a CSU/DSU will be used [...]
In this free CompTIA Network+ training video, I’ll define basic DHCP (Dynamic Host Configuration Protocol) servers and DNS (Domain Name System) servers. I’ll also explain where you might find a basic DHCP server and why they are described as “basic” DHCP servers rather than simply DHCP servers. Finally, I’ll explain what a DNS server is, [...]
Continuing our free CompTIA Network+ training videos on the various network devices included in the exam, I’ll explain what a Wireless Access Point (WAP) is and how it is similar to, but different than a hub. Once you’ve finished this video, be sure to continue your CompTIA Network+ training by learning about other networking devices [...]
In this CompTIA Network+ Training video, I’ll explain what firewalls and proxy servers are and how they work. You’ll learn about their core functions and how they are different from one another. I’ll show you how firewalls control what data is allowed in or out of a network to protect private networks from external intrusion. [...]
In this CompTIA Network+ training video, I’ll go over some of the more advanced functions of switches. I’ll explain each function and give examples of when said functions are generally used. You’ll learn about the following Advanced Switch Functions: Power over Ethernet (PoE, used to transfer electrical power along with data over standard twisted pair [...]
In this video, we’ll be continuing our CompTIA Network+ coverage on network devices. I’ll be going over the different types of switches available including Multilayer Switches and Content Switches. You’ll learn about how multilayer switches provide functionality at higher OSI (Open Systems Interconnection) layers and how content switches actually handle the information being transmitted by [...]
A router is used to connect multiple networks together using sophisticated routing tables, which can determine the best route to get information or data packets from one network to another. The most common types of routers are meant for home users and simply send router information such as web pages, email, and other data from [...]
