Prior to transition, IPv6 must be disabled on all interfaces. If the following registry value does not exist or is not configured as specified, this is a finding: Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\ Value Name: DisabledComponents Type: REG_DWORD Value: 0xff or 0xffffffff If IPv6 transition has been implemented, the following will disable tunnel interfaces allowing native IPv6. Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\ Value Name: DisabledComponents Type: REG_DWORD Value: 0x1 Microsoft updated article 929852 with regard to disabling all IPv6 components, changing the value to 0xff. A value of 0xffffffff results in a 5-second delay in system startup. However, either value can be used to disable all IPv6 components. Documentable: If disabling IPv6 on all interfaces prior to the transition to supporting IPv6 causes issues with necessary applications or services, document this with the IAO. |

Add the following registry values to the system. To disable IPv6 on all interfaces: Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\ Value Name: DisabledComponents Type: REG_DWORD Value: 0xff or 0xffffffff To disable all IPv6 tunneling interfaces: Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\ Value Name: DisabledComponents Type: REG_DWORD Value: 0x1 Microsoft updated article 929852 with regard to disabling all IPv6 components, changing the value to 0xff. A value of 0xffffffff results in a 5-second delay in system startup. However, either value can be used to disable all IPv6 components. |
