Disable Windows IPv6

Sometimes the IP will be IPv6. JetPatch does not support this scenario.

Note: IPv6 needs to be disabled on all windows endpoints and the WSUS server
To fix it, complete the following steps:

1) Disable IPV6 in the Network Adapter

2) Make the registry changes described in this article

3) Reboot the machine

4) Run the following commands:

net stop wuauserv
reg Delete HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate /v PingID /f
reg Delete HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate /v AccountDomainSid /f
reg Delete HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate /v SusClientId /f
reg Delete HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate /v SusClientIDValidation /f
net start wuauserv
wuauclt.exe /resetauthorization /detectnow

5) Reset Windows Update communication to the WSUS:

For Windows version  less than 10/2019:

wuauclt /resetauthorization /detectnow /reportnow

For Windows version 10/2019 or later - 

USOClient.exe RefreshSettings
USOClient.exe StartScan

You can also use the attached script and run it from JetPatch.
