Ammyy Admin is a freeware VPN program which gives you control over a remote computer easily and quickly. Just install the software on each machine, fire it up and one machine selects client and the other operator (the controller). From then on in, it’s a piece of cake for the operator to access the client desktop and do what’s necessary, either for remote support or just to access the stuff on there.
You can transfer files between the two machines and it’s apparently firewall friendly. Unfortunately it’s Windows only, which kind of spoils the party a little if you need to do any cross platform stuff, but whatever.
Ammyy Admin – is a complete system for remote computer access. It’s reliable and accessible way of providing remote computer assistance and remote teaching for your clients, employees, friends or family from anywhere in the world. Ammyy Admin connects remote computers within some seconds and without any installation or configuration. You can view the systems of your clients, and remotely control their keyboard and mouse.
It worked fine for me. Thank you!
