I'm wondering if it is possible to change the DNS-Zone of my DSfW-Server-DNS???

Now - after installing the DSfW with the first server "company.com" is both the DSfW-DNS-ZONE and the real DNS-ZONE of our Company. This is really strange because DSfW-DNS does not know all the hostnames in company.com so I have problems with DNS resolutions with all my clients.

I want to change this - configuring the DSfW-DNS with dsfw.company.com even if the DSfW provisioned eDirectory-structure stays company.com.

Is this possible?
