'mkgroup -lu' error and/or missing group member names

[starlight at binnacle dot cx]

Hello,

When

   mkgroup -lu

is run on a current (as of today) install of CYGWIN 1.7.4,
it returns the error

   mkgroup (376): [1722] The RPC server is unavailable.

Running any of

   mkgroup -l -u
   mkgroup -u -l
   mkgroup -ul

does not result in an error message, but also does not include 
member user IDs in the output:

   Administrators:S-1-5-32-544:544:
   Users:S-1-5-32-545:545:

If 'mkgroup' from CYGWIN 1.5.25 is run under 1.7.4, correct output is 
produced with all combinations of the -l and -u parameters:

   Administrators:S-1-5-32-544:544:Administrator,cyg_server
   Users:S-1-5-32-545:545:testuser,sshd,cyg_server

The 'mkgroup' 1.7.4 behavior appears to be a bug or defect.

CYGWIN is installed on a fully patched 64-bit Windows Server 
2008 R2 system (i.e. Windows 7 or Windows NT 6.1).  System
is a member of a workgroup, not a member of a domain.
