Event ID 34123 — RRAS DHCPv6 Relay Agent Enabling

  • 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. For each IP network segment that contains DHCP clients, either a DHCP server or a computer acting as a DHCPv6 Relay Agent must be enabled.

Event Details

Product: Windows Operating System
ID: 34123
Source: Microsoft-Windows-RasRoutingProtocols-dhcpv6r
Version: 6.0
Symbolic Name: DHCPV6RELAY_INVALID_IF_CONFIG
Message: DHCPV6 Relay Agent could not be configured on the interface. The invalid parameter is: %1, value: %2

Resolve

Reconfigure DHCPv6 Relay or 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 the DHCP Relay Agent" section.
  • This computer might be low on memory. For more information, see the "Check memory usage on the server" section.
  • Restart the computer.

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

Configure the DHCP Relay Agent

To configure the DHCP 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.

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.
