Disable Windows IPv6 on the WSUS Server

Sometimes the WSUS IP will be IPv6. JetPatch does not support this scenario.  In order to account for this, you must disable IPV6 on the WSUS server (including any replicas) at both the network and system level.

Note: In 4.2.4+, you can use our built in script.  If you are using an earlier version, you can upload it into JetPatch (see attached at the bottom of this article).

To fix it, complete the following steps:

1) Disable IPV6 in the Network Adapter Using this Powershell command:

Get-NetAdapter | foreach { Disable-NetAdapterBinding -InterfaceAlias $_.Name -ComponentID ms_tcpip6 }

•  You can check if the IPv6 is successfully disabled using this Powershell command:

Get-NetAdapter | foreach { Get-NetAdapterBinding -InterfaceAlias $_.Name -ComponentID ms_tcpip6 }

2) Disable the IPV6 system component from the registry using this article.

3) Reboot the machine. To check that IPV6 is correctly disabled open a CMD and try:

ping localhost

Note: we have no plans to support IPV6 with WSUS, because in general, unless your domain network is properly configured to handle IPv6, there is no benefit to leaving it enabled as it would cause more harm than good when it comes to domain name resolution and networking.
