AD with FreeNAS8 & ClearOS PDC

[pspreadb]

I'm having a devil of a time trying to get my FreeNAS-8.0.3-RELEASE-p1-x86 (9591) server to use
my ClearOS PDC. I know that the PDC is working since I have other (Windows and Linux) clients
using AD with no problems. I am not a AD expert but I have got a tcpdump trace from the FreeNAS
end. Gollum is the PDC and homenas is the NAS. The following will carry on until it times out and
gives up. Any suggestions as to where to look next for the problem?
