Event ID 10020 Microsoft-Windows-DHCP-Server

Applies To

Windows Server 2008

Dynamic Host Configuration Protocol (DHCP) can lease both Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6) addresses. If IPv6 is not available, the DHCP service uses IPv4 only.

Event Details

Product: Windows Operating System
ID: 10020
Source: Microsoft-Windows-DHCP-Server
Version: 6.0
Symbolic Name: EVENT_DHCPV6_SERVER_NEED_STATIC_IP
Message: This computer has at least one dynamically assigned IPv6 address. For reliable DHCPv6 server operation, you should use only static IPv6 addresses.

Resolve

Configure a static IP address for the DHCP server

To perform these procedures, you must be a member of the Administrators group, or you must have been delegated the appropriate authority.

To configure TCP/IP for static addressing:

  1. At the DHCP server computer, click Start, click Control Panel, double-click Network and Sharing Center, and then click Manage network connections.
  2. Right-click the network connection you want to configure, and then click Properties.
  3. On the Networking tab, click Internet Protocol Version 6 (TCP/IPv6), and then click Properties.
  4. Click Use the following IP address, and then type the IP address, subnet mask, and default gateway.
  5. Click Use the following DNS server addresses.
  6. In Preferred DNS server and Alternate DNS server, type the primary and secondary DNS server addresses.

Verify

To verify that the DHCPv6 service is running:

  1. At the DHCPv6 server computer, click Start, click Run, and then type cmd.
  2. At the command prompt, type sc queryex dhcp.
  3. The DHCPv6 Server service state should be displayed as RUNNING.

  • Hi willockss,

    Thanks for the update.

    However, at a test environment, I cannot reproduce this issue. From the output, it appears that you have setup a IPv6 scope and this server has been assigned. Given
    this situation, please try to deactivate the IPv6 scope first. Then, uninstall
    TCP/IPv6     on this server, to see if this helps.

    For best practices, I suggest that we post this question at Network Infrastructure Services forum. So we can get more effective suggestion by other experts who
    familiar with this topic. Your understanding is highly appreciated.

Every time I restart my server (Windows Server 2008 R2 Enterprise) the following DCHP events appear with the ID 10020 in my event log. I have a static IPv6 address but this event is still being generated.

I searched on the web and on most of the forums are saying if the IPv6 address is static and is configured, to ignore this warning, but I am not so convinced

Event ID:      10020
Source:        Microsoft-Windows-DHCP-Server
Type:          Warning
Description:
This computer has at least one dynamically assigned IPv6 address. For reliable DHCPv6 server operation you should use only static IPv6 addresses.

Event ID 10020 = This computer has at least one dynamically assigned IPv6 address

Having a static IP assigned in IPv6 does not perclude a dynamic IP address assignment. IPv6 is not simply IPv4 with bigger addresses. Check your local and network configruation again.
