How to setup Remote Desktop
Most people use routers and if you are using one you need to not only make changes to your PC settings but also have to add a Port Forward in your Router. You need to get your ISP IP address and you need to set a fixed IP on your PC so first we will address this.
First, on the computer we wish to access, we will go to Properties on MY Computer which is called System in Control Panel.
So either right click on my Computer if you have this on your desktop or go to Start - Control Panel and click on System.
There you will go to the Remote Tab.
Now most important is that you must have a user that has a password set to access this computer.
If you will only have one user then it must be password protected so only those with a password can access the PC using remote access.
So on the System Properties window / Remote Tab:
Check the box under Remote Desktop "Allow users t connect remotely to this computer."
Click on the Select Remote Users.
Add the user you will allow.
Click OK to save on both
Now, if you are using a Router, we must set the IP for this PC.
If your router allows setting a Static IP address for a PC this will make it a bit better.
Better routers have this feature.
If yours does not then we will have to go to the Status window for Network Connection for Local Area Connection.
Go to Start - Control Panel - Network Connections.
Right click on the Local Area Connection and choose Status.
You should get a Local Area Connection window which has two tabs. ( General and Support)
Click on the support tab and then click on the details button.
Write down the default gateway IP address and the two DNS servers addresses.
Close the details window and click on the general tab in the Local Area Connection window.
Now click on the properties tab.
This opens a new window and here we need to highlight the line Internet Protocol (TCP/IP)
Once selected click on properties.
Click on "Use the following IP address"
Fill in the three boxes the following:
IP address: Use your gateway address but add 5 or 10 to the last set of numbers.
For example if you Gateway IP was 192.168.1.1 then make it 192.168.1.6 or 192.168.1.11
Mask: Windows fills this in but if it didn't put 255.255.255.0
Gateway: Type in your gateway address you wrote down.
The next two boxes put the DNS server IP's in each and be sure "Use the following DNS server addresses" is checked.
Save this by clicking OK
Ok now we go to our Router.
We get into the router by typing in the address bar in Internet Explorer the gateway IP address.
Once you type that in a login screen should now be seen.
If you bought the Router the and have not changed the default login look up the default login in your manual.
For most Linksys routers it's admin for the password and the user is blank.
Once in the setup screen navigate to the screen that controls port forwarding.
For low end Linksys routers it's in the gaming screen.
The port to forward is 3389 and there may be two boxes to enter ports in such as start end.
Put 3389 in both and enter the IP address you set for this PC in the IP address box.
Save it and exit.
Go to any website that gives you your IP address.
Just do a search in any Search Engine "Google, Bing, Yahoo" for what is my ip.
Write down the IP address and take it with you to the PC you wish to use to connect to the PC you made these changes to.
On your remote computer click on Start - Programs - Accessories and click on Remote Desktop Connection
In the window type in the IP address you got from what ever website you used to get What is my IP.
If you set it correct you will get a login screen and your now able to access your office or home PC from a remote location.
Now what if you want to have two or more PC's available in the same network remotely.
Well this requires a few more changes.
First you need to make a change to your Windows Registry.
Go to Start - Run and type in regedit.
You will need to navigate to the setting:
HKEY_LOCAL_MACHINE / System / CurrentControlSet / Control / TerminalServer / Winstations / RDP-TCP / PortNumber
The current setting for PortNumber will be 3389 when viewed in decimal - change this to 3390 decimal on the second PC you want to add as a remote access PC in the network and raise this number by one for each additional PC added. A third PC would have 3391 and so on.
Follow the same steps as above but the IP must be set to a different number and in the router you need to add a second port forward using 3390 as the port and the IP you set for this second PC.
To access these other PC's you need to add the port to your IP in the Remote Desktop Connection window. This is done by typing the IP + colon + port number
Thus you would have 555.555.555.555:3390
For the PC that you have set to access.
If you have a Router it's best to turn off the windows firewall as all Routers have firewalls built in.
But if you have your windows firewall on then you need to go to Control Panel - Windows Firewall
Click on Exceptions Tab and click on add port button. Type in a port name - call it remote desktop and type in the port number.
You will need to do this for each PC you setup to access remotely.
