Yes, sorry forgot to include that.

Beautiful, that much is running again, thanks for those pointers.

And I'm ashamed to say I tracked down the issue to a fat finger in the 
resolv.conf file, so it really couldn't look up the needed record :/

So back to the original issue that was in the end because smb wasn't started 
most likely.  I'm still not sure how this will all respond in a multi homed 
environment like this if the IPA server cannot communicate with all of the 
interfaces on the DC.  Will that cause an issue with the trust or is there 
anything I need to take into consideration with this? 

Thanks much
