This article describes the steps to modify Time to Live (TTL) on Domain Name System (DNS) records. Time to Live is used by name servers and some DNS clients to determine the length of time that a name must be cached. In Windows 2000, the default TTL for DNS records is 60 minutes. You can modify the TTL of the record in the DNS Management console.
By default, the TTL field is not displayed on records. If you want the TTL field displayed on records, enable the Advanced View feature.
