David, A few more questions. When you state you cleared the cache I want to insure this meant clearing the Cache on the DNS Server not the client resolver cache. Also if you open the DNS snap-in in advanced mode and look in the cache do you see a record for nyc.test.com and if so can you provide a screenshot of the entry from the DNS MMC? Finally can you go the DNS server open a cmd prompt and launch nslookup. Type "set d2" without the quotes so that you get additional debug output and then type in nyc.test.com and post the output. Why am I asking all of these questions? Well we had a few issues where the DNS servers cache may not correctly cache entries causing the behavior that you are seeing. Sometimes even though you clear the cache if the record is looked up frequently then even clearing the cache will not resolve the issue long enough to see it corrected. I thought that all of these had been addressed by the build that you are running however the output from the above tests should let us see what is going on. Thanks, -Steve

Thanks, -Steve ________________________________ From: [EMAIL PROTECTED] on behalf of Wyatt, David Sent: Fri 7/21/2006 4:39 AM To: [email protected] Subject: [ActiveDir] DNS Issue We have a single Windows 2003 SP1 forest/domain. DCs run AD integated zones. We have Forwarders configured for a domain e.g. test.com with 2 IP addresses entered for the DNS servers in test.com. We have seen a strange issue where queries for a host in the sub-domain nyc.test.com fail (even when doing an nslookup directly from the DC). When we restart the DNS service on the DC resolution succeeds for a host in nyc.test.com. After time it appears resolution fails again. Another observation is when (after time) name resolution fails for a host in nyc.test.com and we explicitly add nyc.test.com as another Forwarder and without restarting the DNS service names in nyc.test.com resolves. Remove the forwarding to nyc.test.com and resolution fails! Any ideas?
