It has been that long since I used 4.1.x, I had to go and do some 
research and yes, it looks like the early Samba DCs used the same DNS 
records as a Windows 2000 DC and you jumping straight to 4.10.2 hasn't 
fixed it ;-)

Andrew, would I be correct in my theory and if so, would joining as a 
4.2 DC fix the dns problem, if not what would ?
