The DFS_INFO_50 structure has the following format.

 typedef struct _DFS_INFO_50 {
   unsigned long NamespaceMajorVersion;
   unsigned long NamespaceMinorVersion;
   unsigned __int64 NamespaceCapabilities;
 } DFS_INFO_50;

NamespaceMajorVersion: A value containing the major version number used to determine the DFS metadata format supported in a domain-based DFS namespace or a stand-alone DFS namespace.<7>

NamespaceMinorVersion: A value containing the minor version number used to determine the DFS metadata format supported in a domain-based DFS namespace or stand-alone DFS namespace.<8>

NamespaceCapabilities: A value containing the capability information of a DFS namespace.
