I have an iMac, and Mac Mini, as well as a Macbook. The mini and the imac are on a gigabit network, the macbook connects wirelessly. All computers are on 10.6.2. Just the other night I was trying to screen share from the imac to the mini. I got an error message stating to connection failed, please check your sharing preferences. All preferences on each machine are the same. The imac cant connect to the mini, but can to macbook, and the macbook cant connect to the mini, but can to the imac. The mini cant connect to either the macbook or the imac. Here is what I have done thus far. 1. Fixed disk permissions. 2. Deleted screenshare.plst 3. Rebooted multiple times 4. Triple checked sharing preferences all preferences on all computers are exactly the same. 5. Disabled ethernet from mac mini, and turned on airport. Was able to connect to imac, and vice versa this way. However is not a optimal solution as gigabit is alot faster then N network. Would rather keep it on gigabit. 6. With the above information, I rebooted the time capsule. As that just screams an ip address issue. Nothing has been able to resolve this issue. The TC is in bridged mode. No settings have been changed. Im out of ideas. I have searched the apple forums but none of the suggestions have helped. Anyone else got any ideas?
