Have you ever called 'net ads join' in a big network with 200 DCs? Once we get
the list with DCs we will resolve *every* name we got to an IP address. Yes,
one would be enough. If we run into timeouts (30sec) a 'net ads join' takes
about 5-10 minutes to succeed.
Take a look at the while loop in discover_dc_dns() :-)
Thanks for looking into this! ;-)
