I am leaning towards the symptoms all point to caching and time outs
resolving some non-Ad records on the internet. One would think that
clearing the cache should fix that tho. Any one have any idea if clearing
DNS cache will leave non-existent records still being cached as
non-existent on that DNS server? I would not think so but I have seen
stranger things.

Records are all there, and the NetLogon restart does nothing as well.
What I have ended up doing is running a simple scheduled batch file at
3:00-4:00 AM everyday to restart DNS on the DC's.
It has definatley reduced the number of incidents, but the odd one still
pops up.

Is the record for the DCs at the site still vaild? It almost sounds like
the record is expiring and the DNS servers will not resolve it.
Does net stop netlogon and then net start netlogon solve the problems?

Thanks James, thought of that route, but got some resistance, may have
to push for it again.
As for flushing the cache, it does not solve the issue, seems as though
a service restart is the only way to go oddly enough??
Cheers

Hi Ertug
Have you tried clearing the cache on the Domain controller DNS and see
if
it works then?
Also, you may want to set up forwarders on your DCs to point at your ISP
DNS servers - chances are they have heavy DNS caches going and will be
able
to resolve external addresses much quicker then using root hings - which
may be timing out causing your DC to cache Domain Not Found for that
query
in its DNS cache.

Guys, have been having a sporadic issue, on my network, both when it was
a
2K Domain and now since the upgrade to 2K3.
Basic Config is: 7 sites - DC - GC - DNS server in each site - WINS in
each
site etc. All DC's are 2K3 AD integrated DNS.
DC's are configured to use internal addresses for DNS.
>From time to time, we have issues resolving a domain name, the name is
not
the same one every time, for example today it was.
http://www.registrefoncier.gouv.qc.ca/
<http://www.registrefoncier.gouv.qc.ca/>
No clients are able to browse to this site, (site not found) my only fix
so
far is to restart the DNS service on the DC for the site having the
issue,
and away goes the problem.
If a client statically enters the external ISP address for DNS
resolution,
it works.
No forwarders specified in DNS.
It is not client/os specific, mix of NT4 - 2K and XP
Anyone seen this before?
Thank you
Ertug
