DNS server machine currently has no DNS domain name

This was a domain controller whose records in DNS were showing only the hostname name of the DC/DNS server. The records in DNS did not show the full internal FQDN. For example, the server name was only displayed, not server.domain.local . Computer group policies would not apply to member computers in the domain. Event ID 414 was being logged on to the DNS event log.
The server was a Windows 2008 R2 domain controller with integrated DNS role. Although this problem is more prevalent with Windows 2003 domain controllers DBNSserver, in this case there is another domain controller on the network to which this server was joined to and promoted to a DC. That other server is a Windows 2003 Windows server.
This was fixed with a simple registry modification that did not even require a reboot. This 100 percent worked for me. Please read here for the steps and details.
