8/30/2023 0 Comments Disable ipv6 loopback windows 10![]() Setting DisabledComponents to 0xff disables all IPv6 components except the IPv6 loopback interface. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters ![]() This is the DisabledComponents REG_DWORD entry which is located here: Disabling IPv6Īs discussed in KB 929852 the IPv6 configuration can be tuned or disabled via the registry. In other words, for IPv6 to be supported IPv4 must also be enabled. Note that a dual stack configuration is required. By leaving IPv6 enabled, you do not disable IPv6-only applications and services (for example, HomeGroup in Windows 7 and DirectAccess in Windows 7 and Windows Server 2008 R2 are IPv6-only) and your hosts can take advantage of IPv6-enhanced connectivity.Įxchange 2007, 2010, and Exchange 2013 support IPv6 with the details for each release contained within the documentation for the relevant product. Therefore, Microsoft recommends that you leave IPv6 enabled, even if you do not have an IPv6-enabled network, either native or tunneled. Moreover, applications that you might not think are using IPv6-such as Remote Assistance, HomeGroup, DirectAccess, and Windows Mail-could be. If IPv6 is disabled on Windows Vista, Windows Server 2008, or later versions, some components will not function. Because Windows was designed specifically with IPv6 present, Microsoft does not perform any testing to determine the effects of disabling IPv6. ![]() This is not true.įrom Microsoft's perspective, IPv6 is a mandatory part of the Windows operating system and it is enabled and included in standard Windows service and application testing during the operating system development process. Others might disable it because of a misperception that having both IPv4 and IPv6 enabled effectively doubles their DNS and Web traffic. Many disable IPv6-based on the assumption that they are not running any applications or services that use it. It is unfortunate that some organizations disable IPv6 on their computers running Windows Vista or Windows Server 2008, where it is installed and enabled by default. Stop, Hammer Time!Īs Joseph Davies very eloquently said back in 2009 : This is pretty frustrating, as this is a well documented process and a quick search using one’s favourite search engine quickly shows the steps required.īut let’s ask if IPv6 really should be disabled. ISATAP is part of the IPv6 protocol stack, so IPv6 is blatantly not disabled on this box…. If we check the IP information we quickly see something like this: There seems to be a belief that the simple act of clearing this ticky box disables IPv6 on the server. When we take a look at the Exchange server, the initial clue is that the network card’s TCP/IPv6 configuration looks like this, where IPv6 is unselected from the NIC. There have been numerous occasions where we have found servers whose admin has said that they have disabled IPv6, but when you look at the server it is not really disabled. When we are performing the Exchange Risk Assessment, one of things PFE love to check is how servers have been configured for IPv6.
