Event ID 34111 — RRAS DHCPv6 Relay Agent Request and Response Operations

  • Article

Applies To: Windows Server 2008

The DHCPv6 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. The DHCPv6 Relay Agent relays DHCP/BOOTP requests and responses from different networks.

Event Details

Product: Windows Operating System
ID: 34111
Source: Microsoft-Windows-RasRoutingProtocols-dhcpv6r
Version: 6.0
Symbolic Name: DHCPV6RELAY_RELAY_FORWARD_FAILED
Message: DHCPV6 Relay Agent was unable to relay a DHCP RELAY FORWARD packet on the local interface with IP address %1; the packet was to have been relayed to the DHCP client with hardware address %2. The data is the error code.

Resolve

Reconfigure the DHCPv6 Relay Agent, check memory status, restart Routing and Remote Access service

Possible resolutions:

  • Reconfigure the DHCPv6 Relay Agent to request notification of events on the socket for the local interface and to relay a DHCP REPLY packet on the local interface. For more information, see the "Configure DHCP Relay Agent" section.
  • This computer might be low on memory. For more information, see the "Check memory usage on the server" section.
  • Stop and restart the Routing and Remote Access service. For more information, see the "Restart the remote access service" section.
  • Restart the computer.

To perform these procedures, you must have membership in Administrators, or you must have been delegated the appropriate authority.

Configure DHCPv6 Relay Agent

To configure the DHCPv6 Relay Agent:

  1. Open Routing and Remote Access. Click Start, click Run, type rrasmgmt.msc, and then press ENTER.
  2. In the console tree, expand IPv6, and then click DHCPv6 Relay Agent.
  3. In the details pane, right-click the interface you want to configure, and then click Properties.
  4. Check that Relay DHCP packets is enabled.

Check memory usage on the server

To check memory usage on the remote access server:

  1. On the remote access server, click Start, click Run, type taskmgr, and then click OK.
  2. In the Windows Task Manager dialog box, click the Performance tab.
  3. Under Physical Memory, check the remote access server's memory usage.
  4. If necessary, free up available memory by ending non-essential applications or processes.

Restart the remote access service

To restart the remote access service:

  1. Open Routing and Remote Access. Click Start, click Run, type rrasmgmt.msc, and then press ENTER.
  2. By default, the local computer is listed as a server. To add another server, in the console tree, right-click Server Status, and then click Add Server. In the Add Server dialog box, click the appropriate option, and then click OK.
  3. In the console tree, right-click the server you want to restart, click All Tasks, and then click Restart.

Verify

To verify that the DHCPv6 Relay Agent is working:

From the router with the DHCPv6 Relay Agent enabled, use the ping command to ping each of the DHCPv6 servers that are configured in the DHCPv6 Relay Agent dialog box on the remote access server.
