Using remote support to repair PCs

A Free Computer technician at your fingertips!
The ever-changing world of computers and technology tends to overwhelm many of us.
When your computer starts acting up or stops working, we have limited sources to turn to. Most of us end up packing up the CPU tower and carting it off to the nearest PC repair technician or company.
That's great for all of us, except that the computer is a spider's web to unravel before you can cart if off, and then you have to put all those wires back in the right place. The best thing you can do is label them, and the ports they plug into, but most of us don't bother to do that, just as we overlook backing up our data.
Wouldn't it be nice to have your PC repaired without taking it to the shop?
In many cases this is possible, and what's more, it can happen free of charge in most cases. That someone can control your PC, diagnose its problem and fix via the Internet, that is called remote support.
Keep in mind, of course, that not all problems can be fixed this way. Your PC first has to be functional enough to be connected to the Internet, or phone line, and you have to be online. Now, there are some products that allow direct connection to your PC from a phone line without being on the Internet.
There are a number of products on the market that allow remote support. Most of them are available for a moderate fee, such as bomgar , Net Support Manager, Remote Admin. You must have messenger installed for this to work, though.
There are also some great free alternatives like RealVNC. MSN Messenger also includes a free remote support client, and Windows XP includes a utility called Remote Assistance. To use these features, you have to prepare your PC for the incoming connection, and allow a particular person permission to access it.
First off, disable the Windows XP firewall (temporarily), or your 3rd party firewall if you are using one, and if you have a router, you will need to allow that incoming connection. For instructions on configuring your router for Remote Support,

Windows firewall can be configured so you can either disable it completely, or to allow certain exceptions. Open Control Panel, then the Firewall icon. Here you can disable the firewall completely, or select the specific applications to allow access. By clicking the Exceptions tab, you can add remote assistance to the list of allowed applications.
You will also need to set remote permissions on your PC. You'll find it in the Control Panel, in the System icon. Locate the tab called Remote and add a check mark for the option to - Allow Remote Assistance Invitations to be sent from this computer.
This will allow you to ask someone for help. This can be someone you trust, maybe someone on MSN Messenger, or someone in your e-mail address book. They will receive your request for help, and can reply to the invitation. They should also have Windows XP and MSN Messenger installed to be able to assist with minimal configuration and compatibility surprises.
Once they have accepted the invitation, you will have to approve the level of support they can give you. You can watch them move your mouse and interact with your PC, you can both operate the mouse and keyboard, or they can have exclusive control over your PC, including the ability to install and remove drivers and applications.
This is a great feature to repair those little annoyances, or minor problems.

How to access your computer remotely

How you choose to access your computer remotely depends on several factors. Your operating system, the type of access you need and the location of the computers.
Windows XP and Server 2000/2003
Microsoft has included a utility called Remote Desktop(RDP) which allows you to connect and operate your computer from another computer just as if you were there. Your desktop appears in a window. Click, drag and drop. Remote Desktop can be configured to use 3 encryption levels.
If you want to transfer files to and from the remote computer more than just a quick copy and paste you will have to use an additional SCP or FTP utility. WinSCP is a very nice free and full featured solution for file transfer in a windows environment.
LINUX/UNIX
Unix devices provide many built in utilities for remote access, control and transfer. FTP(file transfer protocol), SCP(secure copy) and SSH(secure shell) are usually good enough for most needs and are included in the operating system.

Secure CRT from Vandyke Software or PuTTY give you a really nice interface if you are accessing a UNIX box from a windows desktop. Secure and encrypted access to the command line is easy and they also allow for secure FTP (SFTP) transfer within the same utility.
Macintosh OS X
The Mac user has many options especially since OS X is built on a unix kernel. Utilities for remote terminal access allow FTP, SFTP and SSH. There are also remote desktop management utilities available like Remote Desktop 2.
Virtual private network (VPN)
Whenever possible and practical a VPN should be used to connect between locations, especially when connecting over the open Internet. You should never use clear text
