Cannot update a host (A) record TTL property by using the MicrosoftDNS_AType:Modify method in Windows Server 2003

When you try to set the time to live (TTL) property of a host Address (A) resource record to zero in Microsoft Windows Server 2003 by using the MicrosoftDNS_AType:Modify method, the method runs without error. However, when you verify the value of the TTL property by using the DNS tool in Windows or by using Windows Management Instrumentation (WMI), the value is set to 3600 seconds (1 hour).

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

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.
