SYMPTOMS
Your DHCP server that is running Microsoft Windows Server 2003 may not unregister DNS PTR resource records for expired IP address leases. When this condition occurs, you may experience the following symptoms:
 * A backlog of expired leases accumulates on the DHCP server.
 * Network programs cannot connect to network resources.



CAUSE
This problem may occur if the number of expired IP address leases is greater than the maximum number that is specified by the queue limit. When the queue limit is reached, remaining records are not processed until the next registration interval. With this hotfix, you can set the queue limit.
