Periodically have to clear the cache I am also interested in the answers to these questions especially OS version and SP level. We had a few issues with caching around in RTM and a few others around SP1. It is a long story but has to do with how the cache entries are organized in memory. The net affect was that certain lookups would cause the cache to have bad data that would cause the behavior you mention. If you could provide the version of DNS.EXE, full build number using something like filever.exe, that would also be helpful. The last issue I was aware of that exhibited these behaviors is documented here: http://support.microsoft.com/kb/903720/en-us . So I would be interested if you were experiencing the issue with a build beyond that one.

Periodically have to clear the cache How are these servers configured in TCP/IP? Who is forwarding to whom? And what is the SP level? If you want to take this off-list, you can do so by directly emailing me.

Periodically have to clear the cache Hi, I have 4 DNS servers, they are all AD integrated. 2 of them are supposed to be for internal used only, and the other 2 for the internet domain we have, unluckily they we never configured to be split DNS. Anyway, every none and then I have to clear the cache for the internal ones because they stop resolving for certain addresses. Sometimes I also have to update server data files for the DNS server to resolved certain names. Any help on how to troubleshoot this? Thanks Rezuma
