Re: AT&T 4to6 relay not working? said by awasser1: I am still trying to make everything work with windows 7 and server 2008 R2. The server works on ipv6 just fine but the pc computer still tries to pickup ipv4 first. when u put ping -6 it works ok. This is usually caused by windows not *thinking* there is a valid global ipv6 address and route associated with an active network interface.
[snippet from MSDN]
DNS Query Behavior
The DNS Client service in Windows Vista has been designed to minimize the impact on DNS servers when performing DNS name queries through the following behavior:
-If the host has only link-local or Teredo IPv6 addresses assigned, the DNS Client service sends a single query for A records.
-If the host has at least one IPv6 address assigned that is not a link-local or Teredo address, the DNS Client service sends a DNS query for A records and then a separate DNS query to the same DNS server for AAAA records. If an A record query times out or has an error (other than name not found), the corresponding AAAA record query is not sent.

See here: »technet.microsoft.com/en-us/libr···035.aspx
You can see if this is indeed the case by using wireshark or netmon to examine the dns queries/responses.
Good Luck.
