Today (a bit late then all computer expert) I learn about one tools named teamviewer, a tools that allow user to remote access to client terminal. And the coolest thing about the teamviewer is
(2) Easy to use
(3) Secure ( use full encryption based on 1024bit RSA private/public key exchange and 256 Bit AES session encoding)
(4) Support Mobile Platgform
More detail on Teamviewer
You can download the at here and install it.
The step to use is quit straight forward.
(1) Install it
(2) Execute it
(3) Copy the ID and Password pass to the personnel that want to remote access
(4) Use the detail on terminal that want to connect to
That all, simple and nice!!!
