Dynamic Update on DC problem

[dylan]

Hi,

I have read many knowlege base articles on this but am
still unsure of my best course of action. The closest
seems to be Q255913 but Im not sure that it really fits my
position.

I am putting in a new Active Directory domain using
win2000.
I wish to have the DC resolve the domain: mycomp.internal
and forward everything else to my ISPs DNS servers.
This is working fine but ...

I am getting netlogon event 5773 "The DNS server for this
DC does not support dynamic DNS" recommending that i put
netlogon.dns entries into the DC (which is the same server)
Most knowlege base articles reccomend that I then disable
Dynamic Update.

I am not sure of the consequences of this - would this
mean that my server would no longer accept dynamic updates?

Is my DC trying to dynamically update itself of trying to
update my ISPs server, if it is itself then why would it
comlain that it dosent accept dynamic updates?

Can I safely ignore these warnings without adversely
affecting windows services?

1) Make sure the ad zone is dynamic update enabled.
2) make sure the Primary DNS suffix (use ipconfig /all) on the dc is same as
ad zone name.
3) make sure dc points to itself *only in the DNS Servers list (see tcp
properties.) Remove any ISP IP here.
4) setup a forwarder to your ISP and/or use root hints.
5) run dcdiag /fix to update registrations and run a dcdiag again to see if
everything checks out.

thanks,

during one of my demotions/promotions of the dc I had
forgotten to set mycomp.internal zone to be dynamically
updatable.

It sounds like it is try to update your ISP's DNS this is normally seen when
you have your ISP's DNS in your TCP/IP properties remove that if it is there
and all should be well so long as forwarding is working.
