define domain both for internal and external zones?

Sorry for the late response.  Had a hardware failure last night that
took precedence.  Anyway, I got everything working yesterday after I cleared
out a bunch of old experiment zones, including the one you pointed out. 
TSIG is working great and internal and external views are updating 
correctly now. 
Now I'm just reading up on security.
