The only other thing I had odd happen was that I recently added a FreeNAS v8 machine to the network and setup the Active Directory options on it. When I noticed that I could not login to the domain I also found I could not access FreeNAS from my Windows machines, but could access the Apple shares from my Mac. This could just be because AD was hosed to begin with and FreeNAS couldn't access the domain accounts. I don't know if perhaps FreeNAS hosed AD or what. I took that machine off the network, but nothing changed.
