Limit the number of entries that Cygwin fetches from the DC. Also,
starting a cygserver would help.

You may be surprised at how slow a DC really can be when it sees some
load, regardless of connection speed when you try to fetch several
thousand entries. If I were to try a 'mkpasswd -d' on our DC I'd
usually have to wait about an hour with very little network traffic to
show (the resulting file would be about 4MiB).

Achim.
