Hi,

Running the netdiag /fix command on our primary (root) DC (name: KENT,
IP: 192.168.1.2) returns an error:

- Cannot find a primary authoritative DNS server for the name
'kent.companyname'. The name 'kent.companyname' may not be registered
in the DNS.

We have a single label domain, such as: companyname, acting as forest
root.

It is incorrect that the server 'kent.companyname' is not registered
in the DNS as this is the SOA server, a PDC and a root zone server.

I applied the registry settings in MS article
http://support.microsoft.com/?id=300684. This had no effect on the
server behavior.

The root DC's DNS setting is pointing to its own IP 192.168.1.2.

This behavior is causing the NtFrs to fail.

Also, another PDC from an alternate non root domain (with an internet
domain name) cannot register in the root domain's _msdcs DNS
container. The returned error is: ID 5781 - Dynamic registration or
deregistration of one or more DNS records failed...

This is causing a major file replication problem on our network.

I understand that single label domains are a problem. However, we are
stuck with this 'companyname' root domain as our Exchange servers
depend on it.

Any help would be greatly appreciated.

Thank you,

Marko
