Apple’s OS X Leopard (10.5) had problems with accessing Samba shares. Most of them got fixed in late Leopard releases, 10.5.4/10.5.5. During the last Leopard releases the hope arose, that finally OS X will make it into office environments sharing Windows networks.
Then, Apple released Snow Leopard (10.6). Another step into the right direction by providing built-in support for Exchange Server and Google services. But what happened with SMB? The whole story started all over again. While Samba-shares worked pretty well on Leopard, in Snow Leopard all seemed to be messed up again.
