How to Fully Disable IPv6 in Windows Server 2008 R2

It has been ages since my last post, this time I am covering something which is not quite Hyperion-specific: IPv6.

First off IPv6 is the future. We need it. However in Oracle Hyperion EPM installations having IPv6 enabled can definitely cause some issues. So we do need to disable it completely. The steps to do this are not easy to get a hold of.

Run the following commands in a command-prompt:
netsh interface teredo set state disabled
netsh interface ipv6 6to4 set state state=disabled undoonstop=disabled
netsh interface ipv6 isatap set state state=disabled

reg add hklm\system\currentcontrolset\services\tcpip6\parameters /v DisabledComponents /t REG_DWORD /d 255 /f

ipconfig /all


If command prompt shows the above, in Device Manager, disable any ISATAP and 6to4 adapters.

ipconfig /all” should now show the below:

Now reboot:
shutdown /r /t 1
