What are the lights on a network adapter?
One of your customers is not able to browse the Internet from their workstation. When you look at the network adapter, you see that a light is on next to the RJ-45 connector. What does the light indicate?
The invisible network share
You can connect to a network share, but no files are visible and you’re not getting any error messages. Other users of the same share can see hundreds of files. What could be the problem?
Troubleshooting Network Connections
When the network isn’t working, the organization isn’t working. In this video, we’ll show you some command line utilities that can help you find any problems that might be lurking in your network. We’ll demonstrate IPCONFIG, NSLOOKUP, PING, TRACERT, PATHPING, NBTSTAT, and NETSTAT. We’ll also give you some best practices for troubleshooting network interfaces, protocols, and firewalls.
Using the Network
To make the most of a network connection, you’ll need to know how to share files, configure network printers, and setup browser configurations. In this video, we’ll show you how to take advantage of these network resources and how to use Windows services to help manage your network resources.
Installing and Configuring Networks
Before you can use a network, you first need to install and configure the network adapter’s hardware settings, protocols, and client options. In this video, we’ll demonstrate how to setup a wired and wireless adapter in Windows XP and how the protocols and network clients are configured.
Network Topologies
Networks come in many different shapes and sizes. In this video, we’ll discuss the differences in Ethernet, WAN, and Token Ring topologies, and learn about the differences in client/server, peer to peer, and Windows Domain-based technologies. We’ll also take a tour through the myriad wired and wireless technologies, including ISDN, DSL, infrared, Bluetooth, and mobile wireless networks.
Network Cabling
The cable is the important component that links all of our networked devices together, but it’s a critical link that’s often overlooked. In this video, we’ll learn the importance of plenum-rated cable, explore the differences between copper and fiber, and examine network cabling types such as RS-232, USB, and FireWire. We’ll also examine the most common network connector types and discuss some troubleshooting methods you can use to keep your network cabling working perfectly.
Hacking Nmap: Using Nmap to Calculate Network Response Time
“The network is slow!” Almost everyone in Information Technology has heard the cries of the end user community when their important application begins crawling. Because of the complexities associated with modern application infrastructures, technology professionals are often challenged to determine the source of the slowdown. Is the application sluggishness related to the network, security configuration, the end-user workstations, the server, or the application?
