I am running Windows Server 2008 R2, and would like to know how I can disable the 3 tunneling adapters via GPO.

Thanks

You must to create a GPO to modify (or create if not exist) HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\tcpip6\Parameters\DisabledComponents.  If you don't see DisabledComponents, create it by adding the following registry value (DWORD type) with this values:
1 to disable tunnel interfaces
2 to disable 6to4
3 to disable ISATAP
8 to disable Teredo
16 to disable LAN and PPP interfaces
32 to Set preference of IPv4 over IPv6
255 to disable IPv6 completely
