Riiight... leave unnecessary services running, because something unrelated might break. I understand the concern, but I'd still focus minimizing problem vectors over something that may or may not happen. If it happens, then deal with that on a case-by-case basis. I've not encountered any issues regarding disabling IP6 across the board - but, honestly, its crap like that that brings us together here, so I'm not pretending weird things can't and don't happen.
I'm inclined to think that Microsoft wants IP6 running for all the stats they can gather via the Teredo connections. -- Espi On Thu, Sep 19, 2013 at 3:54 PM, Kurt Buff <[email protected]> wrote: > Erm - not so much... > > > http://blogs.technet.com/b/netro/archive/2010/11/24/arguments-against-disabling-ipv6.aspx > and > > http://blogs.technet.com/b/ipv6/archive/2007/11/08/disabling-ipv6-doesn-t-help.aspx > and perhaps > > http://thommck.wordpress.com/2011/02/08/offline-files-versus-vpn-a-k-a-the-case-of-the-missing-work-online-button/ > > Kurt > > On Thu, Sep 19, 2013 at 3:07 PM, Micheal Espinola Jr > <[email protected]> wrote: > > :-) > > > > I just gotta throw-in here that if you don't use it - it should be > disabled > > anyway. > > > > -- > > Espi > > > > > > > > On Thu, Sep 19, 2013 at 1:57 PM, Kurt Buff <[email protected]> wrote: > >> > >> <gasp> > >> > >> Disable IPv6? > >> > >> Heresy... > >> > >> :) > >> > >> Kurt > >> > >> On Thu, Sep 19, 2013 at 1:01 PM, Michael B.
