We have discovered that Windows 2003 server and Windows 2008 R2 have a bug that if your network addresses reside in the public range, such as 162, it will automatically enable IPV6. If you go to regedit and go to local machine -->system -->current control set -->services -->TCPIP6 -->Perameters and set the following: DisabledComponents (32 bit reg DWORD) set to 1 or all f (fffffffffffffff). This will disable IPV6.
