The DHCP traffic is blocked after you enable the "Do not allow exception" and "Prohibit unicast response to multicast or broadcast requests" Windows Firewall settings in Windows 7 or in Windows Server 2008 R2

Applies To
Windows 7 Windows Server 2008 R2

Symptoms

Consider the following scenario:

  • You have a computer that is running Windows Server 2008 R2 or Windows 7.

  • You enable the following Windows Firewall settings by using Group Policy settings or some netsh commands:

    Windows Firewall: Do not allow exception

    Windows Firewall: Prohibit unicast response to multicast or broadcast requests

  • You request an IP address from a DHCP server.

In this scenario, you cannot obtain an IP address from the DHCP server.

If you run the ipconfig /renew command, you receive the following error message:

Note

An error occured while renewing interface name : unable to contact your DHCP server. Request has timed out

  • If at least one of these two Windows Firewall settings is disabled, you can obtain an IP address from the DHCP server.
  • If both of these two Windows Firewall settings are enabled, DHCP traffic is strictly blocked.

      

Cause

This issue occurs because the DHCP traffic is incorrectly blocked.
