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?

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??

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.

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?
