The worldwide scope of an electronic commerce offer must rely on a set of physical and logical solutions to meet users’ expectations. Not all customers are computer wizards, and the architecture must account for ergonomic factors, in addition to the security of the exchanges and the different methods for accessing the telecommunications network. This section […]

How Legal Wire tapping Works
CALEA requires that communications providers allow law enforcement officials to be able to listen in on phone conversations and get information about those phone calls, but only when the law enforcement agency has gotten approval for the tap.
The law enforcement agency goes before a judge and presents reasons a wiretap is […]
Throughout the history of the United States, one of the greatest political tensions has been that which balances personal privacy against the need for law enforcement to protect individuals and the country as a whole.
That tension has been with us from the very earliest days of the Republic. The Founding Fathers were extremely cognizant of […]
If you ask a typical consumer about wireless communications, you might hear about Wi-Fi or wireless Ethernet, but it’s just as likely that cell phones, smartphones, or PDAs with onboard wireless networking would also be part of the conversation. These devices offer web browsing, email, video and still image capture, and text messaging, and they […]
One of the main concerns of network administrators in the 1980s was that any person in the company network could easily install a modem in her computer and connect to computers outside the network. For digital telephone systems, this was not a problem. But for small businesses using an analog telephone system, this could present […]

Because it is usually implemented in a read-only memory (ROM) chip, the BOOTP protocol client is a simple, concise bit of code. The exchange of UDP messages between the client and the BOOTP server consists of a series of requests and replies. The same packet format is used for both types of messages with an […]
Creating an Address Scope
After you have authorized a server on the network, you can create a scope of addresses that the DHCP server can administer to clients. From the MMC utility, click once on the server you want to administer, and then select New Scope from the Action menu. The New Scope Wizard pops up. […]
The Windows 2000/2003 DHCP servers provide support for BOOTP clients. The Default BOOTP user class of options is used to configure the information that is supplied to these clients. Although standard BOOTP servers require that the server be configured in advance with a table of client hardware addresses and corresponding IP addresses, Windows 2000/Server 2003 […]
Many options that can be used for BOOTP and DHCP clients were discussed. The Windows 2000/2003 DHCP service enables you to configure which options will be offered to clients of the service. To configure the options, expand the MMC tree of DHCP servers to locate the server you want to manage. Click that server to […]
If a client is configured to use DHCP, what happens if no DHCP server is available on the network? Starting with Windows 98, Microsoft Windows clients can use Automatic Private IP Addressing (APIPA). This is not a solution for a large network. It is for use on small LANs, such as a home office with […]

If you are using Windows 2000 Advanced Server or Windows Server 2003 Enterprise or Datacenter servers, you can use the clustering feature for DHCP. This allows two separate DHCP servers to be administered as a single DHCP server. Windows 2000/2003 clustering supports a failover mode in which a service running on one computer can be […]
Many small- to medium-sized networks use the router that provides Internet access as a DHCP server, using it to provide network addresses to client PCs. Configuring a router to act as a DHCP server is not difficult (most routers are configured to provide IP addresses by default), but you should be familiar with the process […]
