Incorrect DFS referrals–IPv6, Win7, iSCSI


I have been struggling with an issue concerning Win7 clients, ipv6, and our file servers running DFS.  They would always refer me to the wrong location out of our site.  I have file servers with two NICs on board.  One of these NICs connects the corporate network and the other one connects to a separate vlan for iSCSI.  I have sites setup in AD Sites and Services for all of the subnets, even the iSCSI networks.  What to do?  After some searching I saw a similar post referring to the binding order of your cards.  Lo and Behold moving the corprate lan NIC to the top and the binding order and restarting the DFS service things started working as expected.
