Furthermore, you should disable the option of storing cached credentials by setting the number of cached credentials to 0 in the registry and restarting the computer When you prevent credentials from being cached on the laptop, the user will not be able to log on to.

It has been rumored over the past few years that Internet telephony would one day become so commonplace that the typical phone would become obsolete. After all, why not use your computer to make free calls over the Internet Although that sounds like a great idea, voice calls made over the Internet have been of such poor quality in the past that they were simply too aggravating to use. Internet telephony still needs some time to develop into a robust technology. Still, Windows Messenger includes a voice feature that allows you to use the Internet to have a voice conversation with another person. Your computer (and your contact s computer) needs a sound card, speakers or headphones, and a microphone for this feature to work. Windows Messenger actually works quite well with voice calls, and, depending on networking conditions, these voice calls can sometimes be a viable alternative to a standard telephone call.

his laptop when a domain controller cannot be located to authenticate his credentials. You also should not install any applications locally on the laptop. This means the laptop will have little functionality other than acting as a remote access point to the network, but it will not place precious data or the network in danger.

All the security measures discussed so far are completely dependent on the user properly protecting his laptop or other mobile device. Consequently, you must train users in the potential threats to their laptops and the measures they must take to secure their computers. Although most of the measures users must take to protect their laptops might seem obvious to you such as not leaving a laptop in the car while buying groceries, or at least using a hardware lock to secure the laptop inside the trunk they might not be obvious to your users. As with any type of training, it s best to be creative in how you get your message across to users in a way that they will understand. For example, when explaining to users the level of attention they should give to protecting their laptops, you can use this analogy: tell them to secure their laptops as though they were $2000 bundles of cash. Few people would ever consider locking $2000 in a car or leaving it on a table in a restaurant while they used the restroom. Posters, wallet cards, and e-mail reminders containing laptop security tips are also particularly effective in helping train users.

Windows XP natively supports automatic configuration for the IEEE 802.11 standard for wireless networks, which minimizes the configuration that is required to access wireless networks. Users can roam between different wireless networks without the need to reconfigure the network connection settings on their computer for each location. When a user moves from one wireless network to another, Windows XP searches for available wireless networks and connects to them or prompts the user to select a wireless network to connect to. From a usability standpoint, the automatic and even transparent configuration of wireless networking in Windows XP is great. From a security standpoint, it can present some serious problems. Not all wireless networks are secure, and thus, a user could unwittingly endanger his laptop computer or even the corporate network.

Improving Voice Chat Quality Whenever you chat over the Internet, you ll have better results if you use a headset with a built-in microphone rather than a separate mic and set of speakers. The improvement provided by a headset will be even more dramatic when compared to using the built-in microphone and speakers on a laptop computer.
