We don't use IPv6 and we are not planning to use it. Apparently Windows Server 2008 R2 is installed with IPv6 on by default. We would like to uninstall it or totally disable it. I have unchecked the check boxes that link IPv6 to each network adapter in my servers, but the machines still register IPv6 addresses with the DNS server.
Is there any way to totally remove IPv6 from my network? Or am I missing something? Thanks.

Yes, we've noticed this ourselves. Windows 2008 (and Win 7 for that matter) will use certain tunneling IPv6 addresses. You can turn them off by setting a registry setting. It's described here:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\
Create a new 32-bit DWORD named "DisabledComponents". Set it to 0x01 to disable the tunneling interfaces.
