Help/Explain Text :
Specifies the
Refresh Interval of the domain controller (DC) Locator DNS resource records for
DCs to which this setting is applied. These DNS records are dynamically
registered by the Net Logon service and are used by the Locator algorithm to
locate the DC. This setting may be applied only to DCs using dynamic
update. DCs configured to perform
dynamic registration of the DC Locator DNS resource records periodically
reregister their records with DNS servers, even if their records’ data has not
changed. If authoritative DNS servers are configured to perform scavenging of
the stale records, this reregistration is required to instruct the DNS servers
configured to automatically remove (scavenge) stale records that these records
are current and should be preserved in the database. Warning: If the DNS resource records are
registered in zones with scavenging enabled, the value of this setting should
never be longer than the Refresh Interval configured for these zones. Setting
the Refresh Interval of the DC Locator DNS records to longer than the Refresh
Interval of the DNS zones may result in the undesired deletion of DNS resource
records. To specify the Refresh Interval
of the DC records, click Enabled, and then enter a value larger than 1800. This
value specifies the Refresh Interval of the DC records in seconds (for example,
the value 3600 is 60 minutes). If this
setting is not configured, it is not applied to any DCs, and DCs use their
local configuration.
