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.

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

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

ping localhost
