This sounds like LookupAccountSid fails for some reason.  Is NCBI_NT the
primary domain of the machine as well?  I. e., is the machine in the
same domain as your user account?  If yes, it's very strange that this
should occur.  If you're in another domain, it might be a problem with
domain trusts, but that's just idle musing without knowing what happens
under the hood.

Please start a CMD shell, cd into your Cygwin bin dir and run

  strace -o id.out id

You might want to check the id.out file for sensitive information
(typically environment variables) and you can change group names in
id.out as well as in the id output to hide private info, but the info
should be complete and make sense (i .e, if you change a group name
to XYZ in the id output, change it to XYZ in id.out as well).

Please paste the output of id and attach the id.out file to your reply.


Thanks,
