Natively there is no easy way to do it using group policy.

there is a sample ADMX file below but I have not tested it

DS MVP Ace has a great writeup   http://msmvps.com/blogs/acefekay/archive/2010/05/27/how-to-disable-rss-tcp-chimney-feature-and-ipv6.aspx

By the way it is fine to have it enabled.

Thanks

Mike

You could setup the machines to run a script such as the one I've posted below to disabled the IPv6 components as a whole on every system.

@Echo off
@ECHO Windows Registry Editor Version 5.00 > %TEMP%\DisableIPv6.reg
@ECHO [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters] >> %TEMP%\DisableIPv6.reg
@ECHO "DisabledComponents"=dword:000000ff >> %TEMP%\DisableIPv6.reg
REGEDIT /S %TEMP%\DisableIPv6.reg

Also, take a look at this site:
http://www.curuit.com/how-to-disable-ipv6-via-group-policy-%28gpo%29-20100820459/

That is where I found that script as well as a method for using GPO's within windows.

Take a look at this article on why you may not want to disable IPv6 though, he makes some pretty valid arguments.  It is possible to run both at the same time.  Let me know if youd like more info on how to accomplish that, as there are a few different ways.  Hope this helps!

Thanks.

Actually I think it IS recommended to have both protocols enabled.
That is why it is enabled by default.

Problems using Powershell and Active Directory?

You might wanna keep ipv6 open as there are some apps which work extensively on ipv6.
A better idea would be to configure dns for ipv6/ipv4 coexistence.

Here's a how-to article which you can use.

http://social.technet.microsoft.com/wiki/contents/articles/5927.how-to-disable-ipv6-through-
group-policy.aspx

It has to be said that Microsoft do not encourage disabling IPv6 as elements of the OS will use it.  One example is network discovery - though it will revert to IPv4 as required.

I know in an Enterprise environment, Microsoft have not tested disabling IPv6 so any impact will depend on context.
