Prior to installing MobileMe my four Apple Macs [using an ethernet circuit] was wonderfully stable and functioning. Now I am unable to send emails with Mail and the laptop generally won't connect to the network without lengthy fiddling with settings in the Sharing configuration window - emails continue to arrive thank goodness - mercifully Googlemail is still working so replies can be sent!
An update has arrived on the laptop [around 36 hours after the initial installation] but nothing for the other computers. Anyone have any idea how I can get Mail working again?
