IPv6 LAN question - 6to4 tunneling adapter when using a global IPv4 address privately?
A little background - for historical reasons we use a global IPv4 range on our private LANs (hidden on our private network)
Anyway, ALL the hosts using this global IPv4 range running W7/server2008 are activating their 6to4 tunneling adapters and registering an IPv6 address in DNS. Clients using a private reserved IPv4 address don't activate their 6to4 adapter or have any issue.
We do NOT use IPv6 at all, yet. A client pinging a server (both on the same IPv4 subnet) will now try IPv6 and FAIL. I am concerned this will bite with application response, network shares, almost any problem that will be blamed on 'the network' etc.
MS recommendation is NOT to disable IPv6 components in Windows. What am I supposed to do when MS recommends not disabling IPv6 Windows components but we have absolutely no use for IPv6 on our LAN and it's a potential problem?

what problems are you having? i'm pretty sure any network that supports ipv6 is dual stack meaning it can support both ipv4 and ipv6. that goes for pinging, dns, and everything else.
"We do NOT use IPv6 at all" ... hey speak for yourself. ;-) you sound like a networking tinkerer. have you tried registering for those free ipv6 tunnel providers? then you'll have ipv6 on your lan.
