How to have no DNS cache for a specific domain?

Hi,

There is the scenario. We have a partner who needs to change their IP frequently in their DNS. The problem is we are having a DNS cache so their change doesn't take effect immediately in our side.

Is possible in Windows 2008 or Windows 7 (for users) to remove the cache just for a specific domain?

Thanks

This is the responsibility of the person who  is changing the IP, and updating the authoritative DNS server. Each record has a Time To Live (TTL), which instructs your DNS server how long to cache the record. Typically, this is set to a few days, however, if the an IP changes frequently it should be set to a lower value, maybe 5 mins.

Actually, there isn't a proper way of setting up a DNS server to selectively cache for one DNS zone and not for another.
   
    1: "You ALWAYS want DNS queries to go directly to the source." This is possible, if you own and control the source zone. You will need to set the Zone's TTL to 0. By doing this, the DNS request will NEVER cach amd so every time names are looked for the master DNS server will be queried.

    2: "You want to Black-List some DNS zones." - The solution to this problem will incorporate the one above, but I would advice to create stub zones to nowhere (where the glue records go to nothing) for these zones. A secondary need is usually to capture the data, so you can identify possibly problem clients.
