[Samba] Win2003 DC fails to detect Samba 4 DC

Well, I read several threads on this issue but none solved what I have 
going so I'll re-ask the question: Should I be able to join a Samba 
4.0.7 server to a Windows 2003R2 AD that has been raised to the forest 
level of 2003 and then be able to demote the Win DC? As stated below, 
the Win Admin tools recognize the Samba DC as one of two DCs in the 
domain but the Win DC will not recognize Samba as such when trying to 
demote the Win DC. The FSMO roles will move to the Samba server but the 
DNS MMC will not recognize the Samba DC as a DC either. Is there an easy 
way to orphan the Win DC after just shutting it down? I'd be willing to 
do that.
