   LFN server has a special function
that can be used to know if it is loaded or not:

#define LFNSRV_API                              0x7171
#define LFNSRV_GET_VERSION_INFO                 0x0001
#define LFNSRV_GET_USER_INFO                    0x0002
#define LFNSRV_SET_SFT_INFO                     0x0003

See NTLFN source for more details.
Note that 0x7171 is not in Ralph Brown list yet,
this probably means that normal LFN support (from windows 2000 for instance)
will not support this function.
