How to setup a remote desktop connection?

What is Remote Desktop?
It is a connection to another computer in your home network or just a computer somewhere else in the world.With it you can take over a computer like you are physically sitting in front of that computer.

This could be very useful if for example you are at work or at school and you need some information or documents of your computer at home (which has to be powered on). Using Remote desktop connection you can connect over the internet to you home computer and for example you mail it to your email address at work or school. Now you can view the documents in your inbox there.

Another example of the benefits of it is, if you have a small server at home. Often servers are placed somewhere in the house where nobody comes often like the basement or at the garret. When there was not such thing as Remote desktop connection you had to go to the basement or garret to resolve for example some problems on it or to change some settings.

Using this connection you only need a server without a monitor, keyboard and mouse connected to it and you can place this server for example in the basement or at the garret.

The only thing this server needs is power and to be connected to the network. Using this way you can connect to this server and work on it just as you are sitting in front of it but actually you sit in the living room with a cup of coffee instead of in the basement.

When you connect to your computer at home, it automatically locks that computer so no one else can access your applications and files while you are gone. When you come back to your computer at home, you can unlock it again.

How to setup a remote desktop connection?

How does this it work?

This will be explained below to help you setting up such connection yourself. Just follow the steps below and it would be no problem.

I will explain how it works using the next situation.

I have a computer in the network which I want to access IN the network and OUTSIDE the network. For example from my work.

The computer which I want to access is called:
ComputerHome and has the IP-address 192.155.10.125
This computer is in a network with a couple of other computers and a router.

Remote desktop connection INSIDE the network

Step 1:How to setup a remote desktop connection?
First, on ComputerHome, you need to give permission to let this computer be connected using a such connection. To give the permission you click the right mouse button on ‘My computer’ and then you click ‘Properties’.
The next screen is shown.

Step 2:
In this screen you click the ‘Remote’ tab.
The next screen is shown.

Step 3:
Here you have to check the ‘Allow users to connect remotely to this computer’ checkbox in the ‘Remote Desktop’ block and click ‘Apply’ and then ‘Ok’.
Now the permission to let users connect to ComputerHome is set.
The next step is to test if the connection works already IN the home network.

Step 4:
Maybe you need to restart ComputerHome once, but in all cases this computer has to be powered on.
Now you go to another computer in your network and you:
Click Start -> Programs -> Accessories -> Communications -> Remote Desktop Connection.
The next screen is shown

Step 5:
* Here you can type the name of a computer you want to connect to or select the computer if it has already been entered once. In my example ‘ComputerHome’.
* Or you can type the IP-address of the computer where you want to connect to. In my example ’192.155.10.125′.
* Click ‘Connect’ to connect to the computer.

If you click the ‘Options’ button you can change some settings.
If you click this button the next screen is shown.

Here you can make some settings like visualization, sound or connection speed settings.

Step 6:
If you clicked the ‘Connect’ button the computer will search for the computer in the network and when it will be found, your desktop will change into the desktop of ComputerHome and you can logon using you account on the remote computer (ComputerHome).

If you are logged on to ComputerHome you can work on it just as you are sitting in front of it and you see the desktop of this computer.

To disconnect from ComputerHome you click Start -> Log off or you point the mouse to the top of the screen until a small bar shows up and here you click the ‘X’.

Remote desktop connection OUTSIDE the network

To connect to a computer which is outside the network you can even connect to it using such connection. For example when you are at work or at school and you need to connect to your ComputerHome.
This works almost the same way as using Remote Desktop connection inside the network.

Step 1:
Follow the steps 1, 2 and 3 of Remote desktop connection INSIDE the network and be sure ComputerHome is powered on.

Step 2:
In my example there is a router in the network so first you have to tell this router which computer can be used for a Remote Desktop connection. You need to forward the port to the IP-address of ComputerHome.
The port you need to forward is port 3389 using the ‘NAT’ function in your router.

So in my example you forward port 3389 to IP-address 192.155.10.125.
Now the Remote Desktop connection request comes over the internet to your router and the router says, “oh that’s Remote Desktop” and looks which IP-address belongs to this port 3389. “That’s ComputerHome” and now the request reaches the right computer.

Step 3:
On your computer where you are working on now (work, school or somewhere else outside your home network), open again the Remote Desktop Connection screen by clicking Start -> Programs -> Accessories -> Communications -> Remote Desktop Connection.
The next screen is shown.

Step 4:
Here you type your external IP-address of your home connection. If you don’t know what you home IP-address is you can get it here but do it INSIDE your home network!!! (otherwise you’ll get the IP-address of the network you are physically are).
Or if you have your own domain name which is forwarded to your home IP-address you can also type that domain name here.Then click ‘Connect’ to connect to your ‘ComputerHome’ or if you want to set some options you click the ‘Options’ button first.

After you clicked the ‘Connect’ button, the Remote Desktop connection request will be send over the internet to the IP-address you entered and reaches your router at home. This will forward the request to ComputerHome because you have entered its IP-address in the router.
Now ComputerHome answers the request by giving you the next screen.

If you log on to Windows you see your ComputerHome desktop and you can work on it just as you are sitting in front of it and.

To disconnect from ComputerHome you click Start -> Log off or you point the mouse to the top of the screen until a small bar shows up and here you click the X.
Now you return to the desktop of your computer where you physically sitting in front of, like your computer at work or school.
