IP Address (Internet Protocol Address):
This number is an exclusive number all information technology devices (printers, routers, modems, et al) use which identifies and allows them the ability to communicate with each other on a computer network. There is a standard of communication which is called an Internet Protocol standard (IP). In laymans terms it is the same as your home address. In order for you to receive snail mail at home the sending party must have your correct mailing address (IP address) in your town (network) or you do not receive bills, pizza coupons or your tax refund. The same is true for all equipment on the internet. Without this specific address, information cannot be received. IP addresses may either be assigned permanently for an Email server/Business server or a permanent home resident or temporarily, from a pool of available addresses (first come first serve) from your Internet Service Provider. A permanent number may not be available in all areas and may cost extra so be sure to ask your ISP.
Domain Name Server (DNS): This allows the IP address to be translated to words. It is much easier for us to remember a word than a series of numbers. The same is true for email addresses.
For example, it is much easier for you to remember a web address name such as whatismyip.com than it is to remember 192.168.1.1 or in the case of email it is much easier to remember anonymous@whatismyip.com than anonymous@192.168.1.1
Dynamic IP Address: An IP address that is not static and could change at any time. This IP address is issued to you from a pool of IP addresses allocated by your ISP or DHCP Server. This is for a large number of customers that do not require the same IP Address all the time for a variety of reasons. Your computer will automatically get this number as it logs on to the network and saves you the trouble of having to know details regarding the specific network configurations. This number can be assigned to anyone using a dial-up connection, Wireless and High Speed Internet connections. If you need to run your own email server or web server, it would be best to have a static IP.
Static IP Address: An IP address that is fixed and never changes. This is in contrast to a dynamic IP address which may change at any time. Most ISP's a single static IP or a block of static IP's for a few extra bucks a month.
IP version 4: Currently used by most network devices. However, with more and more computers accessing the internet, IPv4 addresses are running out quickly. Just like in a city, addresses have to be created for new neighborhoods but, if your neighborhood gets too large, you will have to come up with an entire new pool of addresses. IPv4 is limited to 4,294,967,296 addresses.
IP version 5: This is an experimental protocol for UNIX based systems. In keeping with standard UNIX (a computer Operating System) release conventions, all odd-numbered versions are considered experimental. It was never intended to be used by the general public.
IP version 6: The replacement for the aging IPv4. The estimated number of unique addresses for IPv6 is 340,282,366,920,938,463,463,374,607,431,768,211,456 or 2^128.
The old and current standard of addresses was this: 192.168.100.100 the new way can be written different ways but means the same and are all valid:
* 1080:0000:0000:0000:0000:0034:0000:417A
* 1080:0:0:0:0:34:0:417A
* 1080::34:0:417A

Customizing the icon drop shadow effect
Customizing the icon drop shadow effect
One cool new feature of Windows XP is the Use Drop Shadows for Icon Labels on the
Desktop. This new effect really makes the icons stand out from your wallpaper and makes
them much easier to read when you are using a background, such as a photo, that has both
light and dark spots. Unfortunately, depending on your computer’s hardware configuration, you
may or may not be able to experience this cool new effect. If you have a newer computer that
has an average graphics card, you will have no problem using this feature. But if you have an
older graphics card, then you may be out of luck.
The Use Drop Shadows for Icon Labels on the Desktop can be turned on or off. Depending
on the wallpaper that you are using, you may like or dislike the feature. I really like the new
effect, but if you like having a clean and crisp interface, I recommend disabling the effect.
Follow these steps to turn the feature on or off:
1. Click the Start button, and select Run.
2. Key in sysdm.cpl and click OK to launch system properties.
3. Click the Advanced tab, and then click the Settings button under the Performance
section.
4. While on the Visual Effects tab, scroll down to the bottom of the box.
5. Locate Use Drop Shadows for Icon Labels on the Desktop, as shown in Figure 3-1, and
check or uncheck the value, depending on what you would like to do.
6. Click OK to save your changes.
7. Click OK once more to close the System Properties window.

Using Remote Desktop
Using Remote Desktop
You must first enable the Remote Desktop feature on your office computer so that you can control it remotely from another computer. You must be logged on as an administrator or a member of the Administrators group to enable Remote Desktop on your Windows XP Professional-based computer.
To setup your office computer to use Remote Desktop:
Open the System folder in Control Panel. Click Start, point to Settings, click Control Panel, and then double-click the System icon.
On the Remote tab, select the Allow users to connect remotely to this computer check box, as shown below.
Ensure that you have the proper permissions to connect to your computer remotely, and click OK.
Leave your computer running and connected to the company network with Internet access. Lock your computer, and leave your office. The Remote Desktop Connection client software allows a computer running Windows 95, Windows 98, Windows 98 Second Edition, Windows Me, Windows NT 4.0 or Windows 2000 to control your Windows XP Professional computer remotely. The client software is available on the installation CD for Windows XP Professional and Windows XP Home Edition. The client software is installed by default on computers running Windows XP Professional and Windows XP Home Edition.
To install Remote Desktop Connection software on a client computer
Insert the Windows XP compact disc into your CD-ROM drive.
When the Welcome page appears, click Perform additional tasks, and then click Setup Remote Desktop Connection as shown below.
When the installation wizard starts, follow the directions that appear on your screen. Once you have enabled your Windows XP Professional computer to allow remote connections, and installed client software on a Windows-based client computer, you are ready to start a Remote Desktop session.
To create a new Remote Desktop Connection
Open Remote Desktop Connection. (Click Start, point to Programs or All Programs, point to Accessories, point to Communications, and then click Remote Desktop Connection.)

How to login as Administrator in Windows XP?
How to login as Administrator in Windows XP?
The built-in Administrator account is hidden from Welcome Screen when a user account with Administrator privileges exists and enabled. In Windows XP Home Edition, you can login as built-in Administrator in Safe Mode only. For XP Professional, press CTRL + ALT + DEL twice at the Welcome Screen and input your Administrator password in the classic logon window that appears.

Logoff and see if Welcome Screen lists Administrator login. Changes are immediate and you can use the Winkey + L to switch back to Welcome Screen to see Administrator account is listed.
Use this procedure to hide/unhide any user account from the Welcome Screen. Please remember, you can still login to a hidden account using CTRL+ALT+DEL classic logon method, but cannot Fast User Switch to a hidden user account.
Method 2 -
Manual registry edit *
Click Start, Run and type Regedit.exe
