I am looking for a tool that is either free or low cost that works like webex support center. I pretty much need to control a users desktop from anywhere to offer support. Webex is nice since it requires very little user interaction and can traverse almost any firewall. I need something similar to that since there will be many flexible environments I need to support people in. I have looked into remote desktop from windows, and VNC, but they dont fit the bill. Does anyone know of anything?
