nmblookup conflict

What causes this conflict condition in the PDC #1c nmblookup info? This causes Samba not to be
able to authenticate with the given domain controller. Of course, if the smb.conf "password server"
parameter has another (good) DC listed, we get past this, but it kills Samba in single-DC
environments. I've seen this twice in the last three weeks, in two unrelated domains. If the
DC is rebooted, the conflict goes away, and Samba can authenticate again.

(NetBIOS Names and IPs changed to protect the innocent, but the output is real.)
