We live in an age of global communication and connectivity. Could have imagined 10 years ago there was someone who had to sit in a cafe to tell joined a global network, no cable is connected to a laptop, read the latest news or even a game with your friends?
They recommend that you're crazy! Fortunately, this is not the case, and we live in a world where global communication standard, and nearly all have their own permanentConnecting to the Internet via broadband.
What if on this network of communities around the world who could not only read the latest news or view online purchases, you may also remotely control your PC at home! Think about this for a minute, what would be able to do? Would allow applications to remote that you have installed at home, how to use accounting applications, spreadsheets and documents? Leave all the downloads you can check the progress ofhome? Check e-mail only in your mail client from? The possibilities are truly endless. There is a solution at hand, and in this article I will concentrate on using the built-in features of Microsoft Windows XP Professional, that is, remote desktop.
If you have never used Remote Desktop, not to be worried. This is a simple feature that makes it what it is, it gives you the desktop via a client. If you look under "Start -> Programs -> Accessories -> Communications, you willRemote Desktop client application.
With this application you can put a computer or an IP address to connect to connect to. You can even map your home computer hard drives as well, so that appear in Windows Explorer, and also print to the printer next to you, from your home computer on the Internet!
Try at home if you have two computers. You must make sure that Remote Desktop is enabled first, and this can be done by selecting System in the Control Panel, selecting theSecure Remote tab, and that "Allow users to connect remotely to this computer" is selected. If you are planning a house, take note of the name "complete computer", as what you want to enter in the remote desktop client to connect to the computer.
I know they are worried about security at this point, but do not worry - we will talk later.
Well, if you have two computers at home, try and see what happens! They must be presented with the familiarLogin box, and once - ta-da log-in! You are now on the desktop of another computer with remote desktop application on your local computer!
Well - what if this feature could be improved so that you can connect your home PC from anywhere in the world, provided you are connected to the Internet? Fortunately, you can do! There are seven steps that we must do to achieve this goal.
1. Make sure your computer accepts remote desktopHits
2. Make sure your password is strong!
3. Write down your IP address
4. Change the port number that remote desktop responds on (this will help) with safety
5. Ensure that all local firewalls are not blocking the Remote Desktop Port.
6. Create the necessary port forwarding rules on your router
7. Log ignore for a dynamic DNS service (if you have a static IP address from your ISP)
Let me tell you perform these steps and how the individualone.
1. Make sure that your computer will accept requests for Remote Desktop. As above, you must select the System icon in Control Panel, and certainly from the remote adapter that allows users to connect to remote computer "is selected.
2. Make sure your password is strong! If the password is very secure, make sure to change, so that at least 8 characters, at least one uppercase letter and at least one symbol. One way to do this is to serve as symbols / numbers usingSubstitute for the letters. Suppose I wanted my password for my son, Benjamin. Instead of using Benjamin as my password my password, I could use 83nj @ M1N! Which, as you can see, is much more secure than Benjamin.
3. Write down your IP address. We must take note of the internal and external IP addresses. To do this, go to Start -> Run and type cmd. Then click OK. Type ipconfig and look for the IP address entry. In this example we will use 192.168.01. This is your internalIP address. Now go to http://www.whatismyip.com Write down your IP address, in this example we are using 1.2.3.4. This is your external IP address.
Things will get a bit techy 'from that date. The tasks we do are fairly simple, but if you have questions, ask a technical friend first or consult online help from the Internet as an error in the following procedure, the computer may cause malfunctions or if you use an Internet connectionProblems.
4. Change the port number that remote desktop responds on. You must edit the registry. Go to Start -> Run and type regedit. Then click OK and you'll be presented with the Windows registry. I will not go into detail about the registry now, there are books as thick as encyclopedias on the Windows Registry in writing, suffice to say, if you do not know what you do, do not mess with it!
Now when you view the tree
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlTerminal ServerWinstationsRDP TCP. Once there, look for a heading in the right pane named "Port Number". Double-click this entry and select decimal. Now this is 3389 by default. Make sure you change to a number of your choice, in 1024 and under 65,534. In this case, you may 23,456. I recommend that this figure is as dark as possible to prevent the person to discover an open port via portscan on! Click OK and closeRegistry Editor.
A disadvantage of this port that you set can affect the usability of this feature. Some companies are doors that do not lock in common use, so that 23,456 can be blocked. Other companies may all connections, as most home users. If you choose a common interface, such as port 80 or 443, which may allow better access to secure networks, but allows hackers to more easily see your PC via the Internet.
Even with a higher number of leads you will stillvulnerable to certain attacks, but the risk is greatly minimized if you use a larger number of door. I and several colleagues have used this technology for a number of years without incident, but remember, if you connect via the Internet, there is always a risk! This choice of features depends on you.
5. Ensure that all local firewalls are not blocking the Remote Desktop Port. This step is more likely that you will need the instructions provided with the special controlProduct desktop firewall. What you need to do is ensure that nobody is allowed to connect to the port number used previously. This is usually in the form of a firewall rule and looks similar to the following:
That each TCP 23,456 in both directions to connect to the computer. Again, this will require consultation with the instructions for desktop firewall.
Well, before proceeding further it is necessary to ensure that this change is effective. Restart the computer, and youhave another computer on the LAN, try to Remote Desktop on your computer using the number of "port" at the end, for example. MyComputer: 23,456, or your IP address, 192.168.0.1:23456. Make sure it works before or continue, but the next steps will not work.
6. Create the necessary port forwarding rules on your router. This step depends on your particular router. You must connect to invite a port forwarding rule like the following definition:
Anyone can-> Using TCP port 23,456 (replacement for the port number above)) to connect to 192.168.0.1 (replace your internal IP address. You may need the manual for the router via port forwarding request for it. You must define a specific protocol for TCP Server, 23,456 (replacement for the port number specified above). This is the hardest step of all so that I can get some 'on hand.
7. Log ignore for a dynamic DNS service (if you have a static IP addressYour Internet Service Provider). If you can ignore your external IP address never changes, this passage. But if you have a dynamic IP from your ISP, you must perform this step.
This step is to make sure that when you receive an external IP address changes, it will be registered via the Internet, you can still connect to your PC. The best service I have found the use is http://www.dyndns.com.
Subscribe here and enter a host name, which means that you are using myname.dyndns.com want. Follow the instructions hereto ensure that your external IP address will be kept updated on the Internet.
8. Finally, you're ready to go. If you have successfully completed all steps above, you want the test. The best choice is to go to the home of a friend's house with broadband, and then test the connection at a time on the Internet, download the Remote Desktop client is connected, and write both the external IP address or DNS name for example, or 1.2.3.4:23456 myname.dyndns.com: 23456
It is likely that this is notWorking for the first time, I held a contest to be included in each phase can perform to determine if the problem could be.
1. Make sure your computer accepts requests for remote desktop. The best way to verify this, go to Start -> Run and type cmd. Then type telnet 127.0.0.1 portnumber "ie" telnet 127.0.0.1 23,456. "This should be a blank cmd window if successful and returns an error if it did not happen. If this is successful, proceed to the next step. If thishas been unsuccessful, make sure that Remote Desktop connections are enabled on your PC and the port number is correct. You can correct this by typing "telnet 127.0.0.1 3389" in the same CMD window as before, and if this did not happen, not the number of remote port on the desktop yet changed. You may need to restart your PC or check the registry entry above.
2. Make sure your password is strong! This test will leave you to get the password is correct.
3. Write down your IP address. Testthat all IP addresses are correct!
4. Change the port number that remote desktop responds on. You can view this has been set correctly by using Start -> Run and type cmd. Then type telnet 127.0.0.1 portnumber "ie" telnet 127.0.0.1 23,456. "This should be a blank cmd window if successful and returns an error if it did not happen. If this is successful, proceed to the next step. If this does not happened, make sure that Remote Desktop connections are enabled on your PC and the doorNumber is correct. You can correct this by typing "telnet 127.0.0.1 3389" in the same CMD window as before, and if this did not happen, not the number of remote port on the desktop yet changed. You may need to restart your PC or check the registry entry above.
5. Ensure that all local firewalls are not blocking the Remote Desktop Port. The best way to test this functionality, if possible, be used with a PC in your LAN. With the sale of a PC on the same network, telnet, "type", ie "telnet 192.168.0.123,456. "If you get a blank cmd window, then the problem" OK. "If you receive an error message, and all the above tests are successful, then it means that something is blocking the connection to the PC. Give In any local firewalls that can access this (including the built-in firewall Microsoft ), to avoid research.
If this step also works to ensure that your local firewall not only allows the computer network and connect to nothing. I would like to stress once again doBe sure to read the instructions that came with the desktop firewall.
6. Create the necessary port forwarding rules on your router. This is the hardest part of the process. To verify this, you must be on another broadband connection. Once connected, go to Start -> Run and type cmd. Then type telnet ", ie" telnet 1.2.3.4 23,456. Again, this should be a blank cmd window if successful and an error if it did not happen. If all the tests described above weresuccess, and this command fails, then the problem is that there is a problem on the router port forwarding the Remote Desktop application. Be sure to read the manual and the door has successfully transmitted to them.
7. Register to become a dynamic DNS service. You can do this easily by using the command as above. If "portnumber externalip telnet" works and "the port number telnet myname.dyndns.com" is not, then there is a problem with this service. From a CMD window,ping myname.dyndns.com and see if there is an answer. If not, then you must check the online help regarding this service.
It should be, you should connect to your home PC to connect from almost any Internet connection. Remember that you can advanced features of the remote desktop client, such as connecting your local drives, printers, etc.
I suggest you look at the help about everything that comes with the Remote Desktop client can exploreoffer.
As I mentioned earlier in this article, the possibility of such uses are not limits, depending on your needs, and I think the improved technologies, such as 3G and GPRS, the capacity to expand its PDA device so that you can use your home PC to access this switch if you do not carry around a small PC and mini-projector holographic up to date Pocket!

Finding the Best Desktop Computer
With the technology boom stirring up new waves every day, computers have taken a residence in the daily lives of most people, both young and old. There are many options ranging from hand held devices, netbooks, laptop notebooks and the tried and true personal computer. Though it seems that it is becoming the norm to carry a computer of some sort at all times, these portable devices cannot perform with the same strength and agility that a home desktop computer can at the same price point. Picking out a desktop computer may seem like old hat, but just as the face of laptops and netbooks are changing, so is the function of the traditional desktop pc.
Before picking out a desktop, one must first determine the purpose and use for the computer and the performance that will be expected of it. For business use or media use, memory and processing needs to be bigger and faster in comparison to a home computer, which is used mostly for viewing pictures, surfing the web, playing music and creating documents. If gaming however is on the agenda, a faster computer is recommended, as screen lag can become a problem in slower technology. The number of central processors in the computer determine much of these ratios. Though a single is perfectly fine for normal home use, two or more gives a desktop the ability to handle more programs at one time, with speed and efficiency.
Memory and hard drive space are two more components to review before purchasing a desktop computer. Just a few years ago, measuring with gigabytes blew the minds of many techies. Now, tetrabytes are breaking onto the scene with more to offer than ever before. However, for the average home user, a 500 GB hard drive and 1 GB of memory is more than enough space to perform and operate everyday functions.
Once processing speed and memory are taken care of, it's important to consider the available add-on options and features. Most windows operating PC's will offer a trial version of Microsoft Office, though many consumers purchase this package before ever getting their computer out of the box. Anti-Virus software is a must, considering identity theft is through the roof. Other additions could include a DVD burner, Blu-ray player, digital sound, web cam, graphics card, wireless mouse, wireless keyboard, multiple USB ports, card readers or an over-sized monitor. It is no longer unusual to see a twenty-one inch monitor on a desktop computer.
For the novice, purchasing a desktop can be overwhelming. Make sure to shop around and compare prices, as there are specials run daily not only in brick and mortar stores, but on Internet websites and stores as well. Whether online, or in the store, it is important to purchase a computer with full understanding of the purchase, including warranty information and return policies. The desktop is far from obsolete, and is in a market all its own. With competition increasing daily, efficiency and aesthetic appeal are constantly growing, making consumers happier with their choice to purchase a desktop computer.
