Prevent one record from being cached by our DNS Server

Hi,

We use a couple of AD Integrated DNS Servers running on Windows Server 2003. Our servers forward unresolved requests to our BT DNS Servers. This works fine, but we have a problem with one DNS record. Occasionaly the hosting company that provides some services get a rouge error and it means we need to clear the cache on our DNS servers for the system to work again. What i'd like to know is if it is possible to get our DNS servers to always forward the request for this one particular name to the BT servers, and to never cache the record.

Thanks,
Denis

Not unless you can modify the TTL of the record in the primary zone, ie. have BT alter it.  You CAN tell Windows DNS not to cache anything but you can't be that selective.

Other than scripting a (probably pretty ugly) solution, no ... none that I can think of ...
