I'm trying to replace our old Windows 2000 Server by a Windows Server 2008 R2. I followed the guide at MSDN. Coming to the step "Install Active Directory Domain Services..." the option to install the DNS-Server was grayed-out. According to Microsoft Support I skipped the DNS Server Installation at this point. (Because of the single-label DNS name)

I then installed the DNS-Server role and created a forward-lookup-zone for the domain. When running the Best Practices Analyzer of the DNS-Server role I get these two messages for both domain controllers (the old win2k and the new win 2008 R2):

The TechCenter articles suggest to use a proper DNS Server - that's pointless when I try to configure a proper DNS Server.

How do I configure the DNS Server in a way that it resolves these zones? Or are these errors irrelevant?

dcdiag /v /test:DNS

Seems to run fine...
