We live in an age of global communication and connectivity. Could have imagined 10 years ago, someone had to sit in a cafe to say joined a global network, no cable is connected to a laptop, read the latest news or play your friends?

They recommend that you fool! Fortunately, this is not the case, and we live in a world where global communication standard, and almost all have their ownconnection to the Internet via broadband.

And so on the global communications network that can not only read the latest news or visit online shopping, you can also remotely control your PC at home! Think about this for a minute, what would be able to do? Would allow a remote application that is installed at home, how to use accounting applications, spreadsheets and documents? Get all the downloads you can use to examinecarry home? Check e-mail only for the client e-mail? The possibilities are endless. There is a solution at hand, and in this article I will focus on the use of integrated functionality of Microsoft Windows XP Professional, or Remote Desktop.

If you have never used Remote Desktop, do not be worried. This is a simple function that does what it is, it gives you the desktop via a client. If you look under "Start -> Programs -> Accessories ->Communications, you will see a Remote Desktop Client.

With this application you can put a computer or an IP address to connect to connect. You can also connect the unit to your local computer at home, so that they appear in Windows Explorer, and also print to the printer next to you, your home computer on the Internet!

Try at home if you have two computers. You must ensure that Remote Desktop is enabled first, and this can be done by selecting SystemControl Panel, select the Remote tab, check, and that "Allow users to connect remotely to this computer" is selected. If you are thinking at home, take note of the name "complete computer" because that's what you want to enter in the remote desktop client to connect to the computer.

I know you're worried about security at this stage, but do not worry – we will discuss later.

Well, if you have two computers at home, try and see what happens! They must be submittedthe junction box known, and once – ta-da connected! You are now on the desktop of another computer remotely with the desktop application on your local computer!

Well – What happens if this function can be improved so that you can connect your home PC from anywhere in the world, provided that 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 responds to the remote desktop (which helps) safety

5. Ensure that all local firewalls are not blocking the Remote Desktop Port.

6. Create the transmission rules necessary ports 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 your computer accepts requests for Remote Desktop. As above, you must select the System icon in Control Panel, and to get the Remote tab, which allows remote users to connect to the computer "is checked.

2. Make sure your password is strong! If the password is very secure, be sure to change at least 8 characters, at least one uppercase letter and at least one symbol. One way to achieve this is to use symbols / numbers as a substitutefor 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 find the entry IP address. In this example we will use 192.168.01. This is your internal IP address –Address. Now go to http://www.whatismyip.com write your IP address, in this example we use 1.2.3.4. This is your external IP address.

Things get teeny bit of 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 a mistake in these steps below, your computer may cause malfunctions or if you use an Internet connectionProblems.

4. Change the port number that corresponds to the remote desktop. 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 details of the registry today, 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 her!

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. But 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 who is an open port via portscan on! Click OK, then closeRegistry Editor.

A disadvantage of this port on which you decide 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 in May all connections, as many users. If you choose a common interface, such as port 80 or 443, which may allow better access to secure networks, but allow hackers to more easily see your PC via the Internet.

Even with a greater number of leads that you will stillvulnerable to some attacks, but the risk is significantly reduced if you use a higher port number. 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 functions is to you.

5. Ensure that all local firewalls are not blocking the Remote Desktop Port. This step is very likely that you will need the instructions provided with the special controlDesktop Firewall product. What you must do is ensure that everyone can enter the port number used previously. This is usually in the form of a firewall rule and looks like the following:

Allow all 23,456 TCP in both directions to connect to the computer. Again, this would require consultations with the instructions of your desktop firewall.

Well, before going ahead we must ensure that this change is effective. Restart the computer, and youhave another computer on the LAN, try 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 that works before you or to continue, but the next steps will not work.

6. Create the transmission rules necessary ports on your router. This step depends on your particular router. You must log in to invite a port redirect rule, as the following definition:

Anyone can-> When using TCP port 23,456 (substitute the port number above)) to connect to 192.168.0.1 (replace your internal IP address. You may need a manual for your router using port forwarding application for it. It necessary to define a specific protocol for TCP Server, or 23,456 (substitute the port number specified above). This is the hardest step of all so it might take some time to achieve.

7. Log ignore for a dynamic DNS service (if you have a static IP address) From your ISP. 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 ensure that when you receive a change of external IP address will be recorded via the Internet, you can always connect to your PC. The best service I've found is to use http://www.dyndns.com.

Subscribe here and enter a host name, which means that you want to use myname.dyndns.com. Follow the instructionsClick here to make sure 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, then check the connection is the Internet, download the Remote Desktop client is connected, and write 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 have to take exams that can be included in each phase to determine if the problem could be.

1. Make sure your computer accepts requests from remote locations. 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 not successful. If successful, proceed to the next step. If this is not successMake sure that Remote Desktop connections are enabled on your PC and the port number is correct. You can solve this problem, type "telnet 127.0.0.1 3389" in the same CMD window as before, and if not successful, the port number that remote desktop has not changed. You may need to restart your PC or check the registry entry above.

2. Make sure your password is strong! This test, I leave you to get your password is correct.

3. Write down your IP address. Make sure that all your IP –The addresses are correct!

4. Change the port number that corresponds to the remote desktop. You can view this success has been with 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 not successful. If successful, proceed to the next step. If this fails Make sure that Remote Desktop connections are enabled on your PC and the port number is correct. Youcan solve this problem, type "telnet 127.0.0.1 3389" in the same CMD window as before, and if not successful, the port number that remote desktop has not 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 function, if possible, be used with a PC in your LAN. With the sale of a PC on the same network, you type "telnet", ie "telnet 192.168.0.1 23,456. If a blank cmdWindow, then the problem is "OK". If you receive an error message, and all the above tests are inconclusive, it means that something is blocking the connection to the PC. It is necessary in all local firewalls, such as access (including the firewall built into Microsoft) can stop looking.

If this procedure also works to ensure that your local firewall allows not only to computers on the LAN and connect to nothing. I repeat: be sure to read the instructionssupplied with the desktop firewall.

6. Create the transmission rules necessary ports 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 telnet "type", ie "telnet 1.2.3.4 23,456. Again, this should be a blank cmd window if successful and an error if it fails. If all the above tests have been successful and this order isfails, then the problem is that there is a problem with the router port forwarding remote desktop. Be sure to read the manual and the door successfully transferred to them.

7. Register to become a dynamic DNS service. You can easily do this using the command as above. If "telnet externalip portnumber" works and "myname.dyndns.com the port number telnet" is not, then there is a problem with this service. In a CMD window, table and see if myname.dyndns.coman answer. If not, then you should consult the online help regarding this service.

This should be, you should connect to your home PC to connect from virtually 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 get a brief overview of the help that comes with Remote Desktop Client to explore everything it has to offer.

As I saidearlier in this article, the possibilities for such uses are unlimited, depending on your needs, and I think the improved technologies, such as 3G and GPRS, ability to expand your handheld and you can access your home page allows a PC traveling, if not carry around a small PC and mini holographic projector in your pocket up until then!
