    Could be a bad cache file. I had this type of problem on NT4. I had to
    stop the DNS service, copy a new cache file over from the backup or
    template directory under \winnt\system32\dns, restart the DNS service.

    On 2000, you can right click and clear cache.

    I am on 2000 now, so I am not quite sure where that cache file is for NT4.
