MORE INFORMATION

The TTL property of a host Address (A) resource record is the time period, in seconds, that the resource record can be cached by other DNS servers or by a program. When you set a record's TTL to zero, this instructs programs and DNS servers not to cache the record.

The MicrosoftDNS_AType:Modify method is used to update the TTL and the IP address of a host Address (A) resource record by applying the values that are specified as the input parameters of this method. If a new value for a parameter is not specified, the current value for the parameter is not changed. This method returns a reference to the modified object as an output parameter.

If the value of the TTL input parameter is the same as the current TTL value of the resource record, the MicrosoftDNS_AType:Modify method call generates a "Generic Failure" error. This error has an extended error status that is similar to the following:

DNS_RECORD_ALREADY_EXISTS
