Hello, I have tested SMB sharing between Lion and 10.6 or earlier. And I can mount SMB sharing on Lion, but cannot mount SMB sharing of Lion on 10.6 or earlier Mac OS X. (I can connect to the SMB sharing of Lion on Windows 7&XP) I think it may be a bug. But I mind that the SMBX(apple's own implementation of SMB) will not be compatible with SAMBA that earlier Mac OS X versions use. Any thought? Thanks guys.
