Re: DNS stops responding

They are DHCP, yes... I don't have access to a client right now, but since
this problem with recursive query is random in time, are we looking for at
the right side of the problem?

DNS domain name i DHCP options is inko and DNS is 192.168.1.100

BTW: the clients does not appear in DNS... Isn't that default behavior?

Hello Bjørn,

How are your clients configured, DHCP? Please post also an ipconfig /all
from one.

As of now it is the only DNS-server (small domain), yes and yes...

Hello Bjørn,

I assume INKO-FS1 is not the only DNS server? Is Active directory
integrated zones used and do you have a reverse lookup zone
configured?

Hello Bjørn,

Did you run dcdiag and netdiag on the DC's? Please post the result
of it, also post an ipcofig /all from the DC's.

We're experiencing a strange problem on a newly promoted DC.

Every now and then (sometimes daily, sometimes more rare), DNS
stops responding to DNS requests. Service running, but no answer.
We've tried to browse the Event logs, reinstall DNS on DC and so
on... Nothing helps...

The only clue is that recursive query fails (responds to local
lookups, bot not to external)

Server is 2003 R2 SP2

I suspect AD corrupt, but now we need serious help to know where
to start look for erros/misconfiguration/corruption...
