To set aging/scavenging properties for the DNS server

Notes

To perform this procedure, you must be a member of the Administrators group on the local computer, or you must have been delegated the appropriate authority. If the computer is joined to a domain, members of the Domain Admins group might be able to perform this procedure. As a security best practice, consider using Run as to perform this procedure.
To open DNS, click Start, click Control Panel, double-click Administrative Tools, and then double-click DNS.
Aging and scavenging properties configured by this procedure act as server defaults that apply only toward Active Directory-integrated zones. For standard primary zones, you must set the appropriate properties at the applicable zone.
Once you apply changes for server aging/scavenging settings, the DNS console prompts you to confirm. You then have the option to apply your changes to new Active Directory-integrated zones only. If needed, you can also apply your changes to existing Active Directory-integrated zones.
Regardless of whether the Scavenge stale resource records check box is selected as described in step 4, for standard primary zones, this feature is disabled unless manually enabled at the applicable zone.

Open Command Prompt.
Type:

dnscmdServerName**/Config** {/ScavengingInterval Value|/DefaultAgingState Value|/DefaultNoRefreshInterval Value|/DefaultRefreshInterval Value}
