RRAS DHCP Relay Agent Packet Discarding

Updated: December 16, 2008

Applies To: Windows Server 2008 R2

The DHCP Relay Agent is a Bootstrap Protocol (BOOTP) relay agent that relays Dynamic Host Configuration Protocol (DHCP) messages between DHCP clients and DHCP servers on different IP networks. For each IP network segment that contains DHCP clients, either a DHCP server or a computer acting as a DHCP Relay Agent is required.

If the DHCP Relay Agent (IPBOOTP) is discarding packets, DHCP configuration with peer clients and servers might fail.

Events

Event ID Source Message

30016

Microsoft-Windows-RasIpBootp

IPBOOTP has discarded a packet received on the local interface with IP address: %1. The packet had a hop-count of: %2, which is greater than the maximum value allowed in packets received for this interface. The hop-count field in a DHCP REQUEST packet indicates how many times the packet has been forwarded from one relay-agent to another.

30017

Microsoft-Windows-RasIpBootp

IPBOOTP has discarded a packet received on the local interface with IP address: %1. The packet had a seconds-since-boot of: %2, which is less than the minimum value needed for packets to be forwarded on this interface. The seconds-since-boot field in a DHCP REQUEST packet indicates how long the DHCP client machine which sent the packet has been trying to obtain an IP address.

30023

Microsoft-Windows-RasIpBootp

IPBOOTP received a packet which was smaller than the minimum size allowed for DHCP packets. The packet has been discarded. It was received on the local interface with IP address: %1, and it came from a machine with IP address: %2.

30024

Microsoft-Windows-RasIpBootp

IPBOOTP received a packet containing an invalid op-code. The packet has been discarded. It was received on the local interface with IP address: %1, and it came from a machine with IP address: %2.

30025

Microsoft-Windows-RasIpBootp

IPBOOTP could not schedule the processing of a packet received on the local interface with IP address: %1. The packet was received from a machine with IP address: %2. This error may have been caused by a memory allocation failure.The data is the error code.
