Does not RoundRobin based on user name. Try using nslookup and/or dig to
make directed queries. nslookup and dig do not use the dns client resolver,
so you can cross that off the list when using them. If RR is on at the
server, you should see records go around. Also make sure netmask ordering
is not checked on. Please post your dig output if still having issues.
