Determines which events the DNS server records in its transaction log, Dns.log.
LogLevel is a 32-bit binary value. To direct DNS to log a type of event, the DNS console sets the value of this entry to the value representing that event type, as listed below. To direct DNS to log more than one type of event, the DNS console sets the value of this entry to the sum of the values representing each event type you want to include in the log.
To get a complete log, set the value of this entry to 0x8100F331.

To change the value of this entry, use the DNS console. Right-click the server name, click Properties, click the Logging tab. This bitmask corresponds to the check boxes in the Debug logging options section. Do not change this value by editing the registry.
DNS reads its registry entries only when it starts. You can change entries while the DNS server is running by using the DNS console. If you change entries by editing the registry, the changes are not effective until you restart the DNS server.
