I just upgraded both machines to Lion Both machines were 100% working with SL 2010 iMac and 2010 MacBook Pro the iMac can connect to the MBP, share its screen & see the shared folders without any issues the MBP however can share screen but gives "connection failed" error when trying to see the shared folders on the iMac. I didnt change any login/passwords or settings during the upgrade to Lion. I've checked the shared folder prefs and everything seems as it should. I switched the accounts to connect via Apple ID, a new Lion feature, but i get the same connection failed error. Any suggestions?
