2. Choose Sharing
3. Turn On Screen Sharing. Make sure it's on and "Allow Access for all users" (especially if you are using Mac OS X Lion)"
If you have Mac firewall enabled, you might need to make sure it's not blocking connection.
System Preferences -> Personal , Security -> Firewall
If it's off, then you are fine and do not need further action on firewall; if it's on, click "Advanced" make sure you see "Remote managment allow incoming connections" has a green light, if not, uncheck "Block all incoming connections" and check "Automatically allow signed software to receive incoming connections".
