The new SMB2 stack deliverd with OS X 10.9 (Mavericks) often fails to connect to NAS devices or behaves strangely on server volumes, such as an inability to change file/folder names.
Some possible workarounds are:
First try using cifs:// instead of smb:// to connect to the server volumes.
If that doesn't help, then there is a way to change all connections that use SMB1 by entering this command in Terminal:
To restore the default SMB2 you simply need to delete the newly created configuration file (nsmb.conf) with the command:
Both workarounds force OS X to use SMB1 as a network protocol instead of the default SMB2 used by OS X 10.9 (Mavericks). While the first is an ad hoc solution the second is a persistent but reversible configuration change (for this user account). SMB1 is slower than SMB2 but stable.
