Well, we started with one server (DC). This server is master. Changed the 
zone from standalone to AD integrated.
Installed second machine, which results in a running, but empty DNS-server. 
We promoted this server also to DC. After haveing replicated AD, the next 
reboot shows a full flying DNS-server with same zones (serial quirks) but 
having his name as master. We tried to change the SOA record back to 
server1 - without look.
Afais, we have two masters, which makes 'sense' as both can accept dynamic 
updates. I one DC fails, the other can still accept.
