Having a unique identifier (UID) to identify a customer across multiple databases is an important—and frequently overlooked—concept. In the traditional world of direct marketing, a combination of name and address, and sometimes telephone number, is normally used to uniquely identify each customer. But because of the likelihood of misspelling names and transposing numbers, this approach […]
Because member and customer data are among the most valuable assets your company has, guaranteeing their security and integrity is critical. Customers want to be sure that information about their preferences and behavior will remain private and won’t end up in the wrong hands. If you can’t give your customers that assurance or control who […]
Nevertheless, the transformation of the county fair into a supermarket is taking longer than originally anticipated. Use of the Internet for economic exchange clashes with the culture of freely available information, absence of a central authority, and the legitimate concerns regarding the security of information on the network. Security on the Internet is an afterthought; […]
The arguments in favor of the Internet sound, at a decade interval, like an echo of those that were previously formulated in praise of the Minitel. This passion for information technology is displayed in a context where ambitious growth rates are not physically sustainable, due to market saturation in rich countries, the progressive depletion of […]

The automation and dematerialization of monetary exchanges are not objectives per se, but are solely means to improve the productivity of financial institutions. In this regard, an overabundance of standards, and sometimes their competition, may constitute a barrier to the establishment of electronic commerce. Even if some manufacturers think they can profit from this situation, […]
The modern monetary system freed itself of material support by replacing it with a generalized system of trust based on continuous growth. In the past, monetary creation was absolutely limited by the scarcity of materials to be exchanged or of precious metals for minting coins. Now, however, money liberated from a material basis, in particular […]
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 […]
TCP/IP was built using a layered approach. You may have heard about the OSI (Open Systems Interconnect or Open Systems Interconnection) Reference model that is used mostly as a framework around which a discussion of network protocols can be discussed. Developed in 1984 by the International Organization for Standardization (ISO), this model defines a protocol […]
Similar to BOOTP, DHCP uses a request/reply mechanism, and the packet format is almost the same for both to provide for backward compatibility. The layout of the packet used by DHCP looks very much like the layout of the BOOTP packet, with a few exceptions. The first 11 fields are the same. However, the last […]
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. […]
Installing a DHCP server on Windows 2000 or Windows 2003 Servers is just as simple as most application installs. However, you’ll need to have some information ready before you begin the installation. You will need to know the range of addresses that the server will administer and lease to clients. If you have any servers […]
Objects and Attributes
For the most part, an object is nothing more than a collection of specific pieces of information about the object. For example, an object that represents a user account contains attributes that hold information about the particular user. When you create user accounts in the Active Directory, you supply the same information that […]
Directory services should make things easier, not more difficult. Microsoft’s Active Directory (as well as other LDAP-based directories) uses the hierarchical treelike organization as spelled out by the X.500 standards, but the Active Directory also adapts the Windows NT domain system, by using DNS as a locator service, to the structure. That is, in addition […]
If you are an article or rewrite article writer, you may said that if all your articles pass a copy scan, for sure you can make a lot of money, right? So, from which source except copy scan that costs you in order to check your article and grammar using their service.
You can excel by […]
Okay, it’s time to illustrate how the AD installation process works under Windows Server 2003. The example here is based on the Enterprise edition, but the process is similar for all other Windows Server 2003 variants (except for the web edition). To install the Active Directory on Windows Server 2003, follow these steps:
The first window […]
Master Maps
The automount daemon uses the master map to obtain a list of maps. The master map also contains mount options for those maps. The master map file is usually named /et c/ auto .master. The syntax for the entries in this file is as follows:
mount-point map [mount-options]
mount-point is the pathname of the local directory […]
