Reset scavenging and aging properties for a specified resource record

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2

To reset scavenging and aging properties for a specified resource record

Open DNS.
In the console tree, click the applicable zone.
In the details pane, double-click the resource record for which you want to reset scavenging and aging properties.
Depending on the how the resource record was originally added to the zone, do one of the following:
- If the record was added dynamically using dynamic update, you can clear the Delete this record when it becomes stale check box to prevent its aging or potential removal during the scavenging process. If dynamic updates to this record continue to occur, the DNS server will always reset this check box so that the dynamically updated record can be deleted.
- If you added the record statically, you can select Delete this record when it becomes stale check box to permit its aging or potential removal during the scavenging process.

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.
This procedure is only necessary for resource records that are dynamically registered. For records that you manually add to a zone, a time stamp value of zero always applies to the record, excluding it from the scavenging process.
Scavenging and aging properties for NS and SOA resource records are reset in the properties for the zone, not the properties for the resource record.

Open Command Prompt.
Type: dnscmd ServerName /Config {ZoneName|..AllZones} /ScavengingInterval Value

Value	Description
dnscmd	Specifies the name of the command-line program.
ServerName	Required. Specifies the DNS host name of the DNS server. You can also type the IP address of the DNS server. To specify the DNS server on the local computer, you can also type a period (.)
/Config	Required. Specifies the configuration command.
