A child server's domain name may continue to be resolved by the child server even after the parent server revokes the NS record for the child server.
A client will still use the revoked child server after it is revoked.
* Steady series of DNS queries for a domain name in the child server. * The TTL for the domain name. A record is shorter than the TTL for the NS record for the child name server. * The NS record is removed from the parent server.
Restart the TMM to clear out the cache.
The TTL is updated for equally trusted records only.
