Disable Windows IPv6 on the WSUS Server

Sometimes the 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).

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 }

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

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

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

ping localhost

If the Output show you "::1" then IPv6 is not fully diabled and you will have to disabled the component from the registry using this article.
