My snow leopard (10.6.7) suddenly refused to connect to another mac (snow leopard 10.6.4) through screen sharing. There is no change except the installation of the latest security update.
If I connect using "MyComputer.local", it tries until timeout with no error message. If I connect using IP address (192.168.0.X), it tries and manage to make the connection only after one minute.
I do not have the same problem connecting with other devices on the same home network, but none of them is snow leopard.
Any help will be appreciated.
