A Guide to Windows 7 Networking

For home, the office, or in between, here's how to set up a network with Windows 7

Whether at home or at the office, networking has gone mainstream. Once upon a time, a computer had value as a stand-alone machine running applications, but that time has passed. Without an ability to access the Internet, retrieve e-mail, chat via instant messaging, and connect with file shares and software, the computer is little more than an expensive paperweight.

Clearly, the trend is toward remote and mobile computing, and it's important for an operating system to provide the tools necessary to remain connected and productive from anywhere. Microsoft is incorporating a variety of new networking features in Windows 7 that simplify connectivity and help users access network resources no matter where they are connecting from. Here we'll take a closer look at some of the innovative networking features to be found in Windows 7 (we may get a little bit technical at times).

HomeGroup

Let's start with an enhancement aimed primarily at home users and home businesses: With Windows 7, Microsoft introduces the concept of HomeGroup. The HomeGroup feature serves two primary purposes: (1) to make sharing files and resources between computers on a home network easier, and (2) to protect shared files and resources from guests or wireless-network intruders.

Many homes have multiple computers, and users want to be able to share music and pictures, or network all of the computers so as to print to a single printer. This type of local area networking has been possible in Windows for years, but it has often been easier said than done, leading to many hours of user frustration.

Open HomeGroup from the Control Panel. Click on Create a HomeGroup to begin the process. You can determine the types of files or content that you want to share with the HomeGroup by checking or unchecking the appropriate boxes.

After you click Next to create the HomeGroup, Windows 7 will automatically generate a password that other users will need in order to join the HomeGroup and share the resources. Windows 7 Starter and Windows 7 Home Basic versions cannot create a HomeGroup, but computers running any version of Windows 7 can join a HomeGroup. One significant drawback to the HomeGroup concept is that it works only with Windows 7, so any Windows XP or Windows Vista systems in the home will not be able to participate.

Using a HomeGroup simplifies the process of sharing files, folders, and other network resources with trusted computers on your home network. At the same time, it enables you to allow visiting guests to connect to your wireless network for Internet access without also granting them access to the shared content and resources. It also prevents any unauthorized rogue wireless connections from gaining access to shared resources.

VPN Reconnect

Roaming users rely on VPNs (virtual private networks) to provide a secure connection between their computer and the internal company network. When a user is sitting in a hotel room, or in a conference room at a customer site, and establishes a VPN connection, the user's PC will generally remain connected unless there is some other network issue that interrupts the connection.

However, users who rely on wireless broadband connectivity to establish a VPN connection while on the move are faced with frequent dropped connections and a cumbersome process for reauthenticating and reestablishing the VPN connection each time.

The VPN Reconnect feature allows Windows 7 to automatically reestablish active VPN connections when Internet connectivity is interrupted. As soon as Windows 7 reconnects with the Internet, Windows 7 will also reconnect with the VPN. The VPN will still be unavailable as long as the Internet connection is down, and the process of reconnecting will take a few seconds after Internet access becomes available again, but VPN Reconnect will ensure that users stay connected with the network resources they need access to.

VPN Reconnect is basically an IPSec tunnel using the IKEv2 (Internet Key Exchange) protocol for key negotiation and for transmission of ESP (Encapsulating Security Payload) packets. ESP is part of the IPSec security architecture that provides confidentiality, authentication of data origin, and connectionless integrity.

In situations such as viewing streaming video over a VPN connection while riding on a commuter train, users typically lose all buffered data and have to start the video over every time connectivity is lost. The features of the IKEv2 IPSec tunnel and ESP help ensure a persistent connection even if the IP address changes during the reconnect and allows the streaming video to resume from the point it was at when VPN connectivity was lost.

I’d recommend a Dell XPS 15 2-in-1 and the new Windows 10 to anyone who needs to get serious work done (before you kick back on your couch with your favourite Netflix show.)

I need power and lots of it. As a Front End Web developer anything less just won’t cut it which is why the MSI GT75 is an outstanding laptop for me. It’s a sleek and futuristic looking, high quality, beast that has a touch of sci-fi flare about it.

If you can afford the price tag, it is well worth the money. It out performs any other laptop I have tried for gaming, and the transportable design and incredible display also make it ideal for work.
