Hi there!

I'm a newby on DNS and I'm being fixing our servers on the small ISP where I
work.
I switch the slave server to master and master to slave becouse to match the
ips with our domain registry in the order of NS1.DATACOURSE.NET and
NS2.DATACOURSE.NET, and now I'm getting this messages each time I restart
the services
