Windows 2008 Server DNS Cache Bug ?
2008 June 2 – 4:59 pm
A few times now we’ve spotted what looks like a bug with the Windows 2008 Server’s DNS Cache. Every few months clients don’t get a response to DNS queries with the answer is already in the cache. Removing the entry from the DNS server cache does nothing but clearing the entire cache fixes the problem in seconds.
We’ve still not quite pinned it down hence the we think there’s a bug. We’ll continue to monitor this which I’m sure is just something not quite right that we’ve done somewhere.
But of course comments welcome.

Hi,
I googled this blog in regarding of an issue i noticed by a client.
I had to manually clear the DNS cache because it contained old cached records and clients complained they could not reach some websites anymore.
I suppose the cache should obey the TTL of the cached records and no other config is possible on the cache?.
Anyway, i will keep an eye on this cache issue.
Regards!
