The loopback UNC path (a UNC path whose server name is localhost, 127.0.0.1, or the local machine name) is not supported. As a special case, [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] using File Server Cluster which is hosted on the same node [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] is running is also not supported. To prevent this situation, it is recommended that [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] and File Server Cluster to be created on separated Windows Clusters.

## Operating system considerations (SMB Protocol vs. [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)])

Different Windows operating systems has different SMB protocol versions, and the SMB protocol version is transparent to [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)]. You can find the benefits of different SMB protocol versions with respect to [!INCLUDE[ssnoversion](../../includes/ssnoversion-md.md)].
