Re: WIndows Updates Fail Via IPv6

["Morgan A. Miskell" <morgan.miskell () caro net>]

Not to beat a dead horse, but could the problem be so simple?  I have 
tons of dual-stacked machines that have updated forever without issue, 
so I assume they update via IPV4.

That being said, I've not packet sniffed any of the update stuff in a 
while but if the DNS is any indication then dual-stacked machines can 
update via IPV4 while IPV6 ONLY machines will likely fail since the DNS 
shows IPV4 only....

host windowsupdate.microsoft.com
windowsupdate.microsoft.com is an alias for 
windowsupdate.redir.update.microsoft.com.nsatc.net.
windowsupdate.redir.update.microsoft.com.nsatc.net is an alias for 
redir.update.microsoft.com.nsatc.net.
redir.update.microsoft.com.nsatc.net has address 157.56.77.153
