Routine Description:
This routine processes the server half of NetStatisticsGet in
the server FSD.
Arguments:
Srp - a pointer to the server request packet that contains all
the information necessary to satisfy the request. This includes:
INPUT:
Flags - MBZ
OUTPUT:
Not used.
Buffer - a pointer to a STAT_SERVER_0 structure for the new share.
BufferLength - total length of this buffer.
Return Value:
NTSTATUS - result of operation to return to the server service.
