TeamViewer is our solution for easy and friendly desktop sharing. You can remote control a partner’s desktop to give online assistance, or you can show your screen to a customer - all without worrying about firewalls, IP addresses and NAT.
To connect to another computer just run TeamViewer on both
machines without the need of an installation procedure. With the first
start automatic partner IDs are generated on both computers. Just enter
your partner's ID into TeamViewer and the connection is
established immediately.
