Slow dynamic dns registration

Hi,

I have a test w2k AD domain with about 5 w2k clients.

Everything seems to be fine by the dns server side. The clients can logon to
the domain very fast and there is no dns errors in the event logs. The AD
looks and feels to work well. The automatic dynamic dns registration of the
clients fails, however.

If I type ipconfig /registerdns in cmd window, the clients A record shows up
immediately in the dns server. However, the PTR record is not updated,
although I have created the reverse lookup zone for my domain.

There is only one internal dns server address in each workstations tcp/ip
settings. The forwarders work very well.

How long should I typically wait for clients ddns registration and what can
cause that the automatic registration fails?

Should happen at the same time as the FLZ, do you have Dynamic updates set
to "yes" on the reverse lookup zone?

And is the reverse zone created properly to reflect the actual subnet?

Oops! There was an mistake. Now both zones are updated. But not
automatically. It still requires ipconfig /registerdns at the workstation.

Well. The dns update works if i enter ipconfig /registerdns AND when I
reboot the client machine.

But shouldn't the update work also on the fly if I remove the records from
the dns server and wait for a while?

On a workstation, no. Either during the ipconfig or during reboot it will.

If a DC, the netlogon service will do it every 60 minutes with W2k. W2k3
does it every 24 hours.
