[Samba] sys_gethostbyname error causing large delay in sessionsetup

I have looked through my smb.conf, my logs, and everything else, but I am
not running with any "hosts allow" settings, and the error is at log level
0, so that does not help.  The interesting party is that it finds the
correct ip for the workstation.  The only other instance of this problem
was reported to the list back in 1997.  This is really slowing down my
users and some are quite angry with me(though this is normal).
The slowdown seems to only effect most, but not all users, both NT4 and
I hope you can think of something other than enumerating in hosts (too many
workstations + DHCP + ip renumbering coming up).

Thank you for your time,

Do you have "hosts allow = <hostnames>"?  Try using the IP addresses
in this line instead.  Also try setting "log level = 0".
