We have several MacBooks on Mac OS 10.6.8 and 10.7.5 that need to connect to MS Server 2012 SMB shares. These machines don't have a problem connecting to Server 2003 or 2008 SMB shares. Normally we just do a "command + k" to open the server dialogue, put in the smb://server address, authenticate with credentials and get a list of available shares.
Now we get the "There was a problem connecting to the server "server address" error message.
Our MS Server 2012 is sharing via SMB protocol and is visible on the network. It is also pingable from the MacBook Pro. It seems strange that we can ping it, but not connect to it. It doesn't even try to authenticate, which seems to me like some kind of protocol issue, but I don't know enough about that. Does anyone know what this issue is or experienced similar?
