ddns-client-fqdn indicates the client performed updates on the forward
records (or told the server it would, and as it turned out was not able
to because it doesn't have the keys necessary).
As it turns out, most windows boxes think they are allowed to update
their A record by default (using something called GSS-TSIG). See also
the as112.net project.
You can guide wether the server will allow client-updates with the
'allow/deny client-updates;' configuration variable.
