• Disabling IPv6 is Windows 10 is confirmed to break many components of Windows, such as any UWP (Unified Windows Platform) application, and many Windows Updates which will fail to install
• A networking issue has been detirmined to be caused by Windows preferring IPv6 addressing over IPv4 Addressing

Set Windows to prefer using IPv4 address over IPv6 by following one of the options below: (Must be done on both the server and the workstations)

Option 1: Modify the registry

1. Refer to Microsoft KB https://docs.microsoft.com/en-US/troubleshoot/windows-server/networking/configure-ipv6-in-windows.
2. The Microsoft Fixit tool has been retired.

Option 2: Manually Edit Windows Registry

1. Open Regedit - press Windows+R keys, type "Regedit" in the Run window, Enter.
2. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters.
3. Double-click on DisabledComponents, if DisabledComponents is unavailable, you must create it; otherwise skip to step 5:
   1. Right-click on Parameters (in the left pane)
   2. Select New, then DWORD (32-bit) Value
   3. Enter "DisabledComponents" and then press Enter
4. Double-click DisabledComponents.
5. Change the Value data to "20" and the Base setting to "Hexadecimal".
6. After modifying this value, Reboot the workstation, and windows will default to IPv4.

Option 3: Run a netsh command

1. From an elevated CMD prompt run: netsh interface ipv6 set prefixpolicy ::ffff:0:0/96 46 4.
   • This will set the precedence of IPV4 to 46 just below localhost (50)
