Updated: December 16, 2008

Applies To: Windows Server 2008 R2

red

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.

After the DHCP Relay Agent (IPBOOTP) is initialized, the DHCP Relay Agent can relay DHCP/BOOTP requests and responses from different networks.

Resolve

Remove and reinstall the DHCP Relay Agent, check memory status, or restart Routing and Remote Access service

Possible resolutions:

  • Remove and reinstall the DHCP Relay Agent. For more information, see the "Remove and reinstall the DHCP Relay Agent" section.
  • Check the protocol message for parameters that are not valid. Create the event with valid parameters.
  • 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 be a member of the Administrators group, or you must have been delegated the appropriate authority.

Remove and reinstall the DHCP Relay Agent

To remove and reinstall 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 IPv4, right-click DHCP Relay Agent, and then click Delete.
  3. Click Yes to confirm the deletion.
  4. Under IPv4, right-click General, and then click New Routing Protocol.
  5. Click DHCP Relay Agent, and then click OK.

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 DHCP Relay Agent is working:

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