Thought for sure this was a real bug, but you are correct Mr. Bartlett,
thats just how the SMB protocol works. I verified this with another
wireshark capture from the same XP machine and a working SAMBA4 appliance
from Sernet. This second capture also reveals that bind9 is still having
issues on the SOGo appliance. The host machine registers itself into the
DNS zone, but will not add client machines when they try to join the
domain. How do I use the internal DNS service with SAMBA4?
