If you defined a static IP address for a network device, duplicate IP address conflicts may occur on a DHCP network. See more details.

To resolve it, convert the network device with the static IP address to a DHCP client. Or, you can exclude the static IP address from the DHCP scope on the DHCP server.

  1. Turn off the DHCP client computer in conflict with the network device that has the static IP address.

  2. On the DHCP server, exclude the static IP address from the scope of the DHCP IP address range.

  3. Restart the DHCP client computer.

Note If the conflict persists for a Windows for Workgroups 3.11 client computer, delete the DHCP.bin file in the Windows directory before you start Windows for Workgroups.

Common scenarios of duplicate IP address conflicts

Scenario 1A static IP address is defined for a network device, for example, a printer. When you install a DHCP server, duplicate IP address conflicts may occur between the network device and a DHCP client computer (running Windows for Workgroups or Windows NT).

Scenario 2You manually define static IP addresses for network devices and computers during a network link failure to a DHCP server. When the link is then reestablished, the conflict occurs.
