I have a Windows 7 machine that seems to always have some DNS servers that were retrieved from some previous connection. They seem to take precedence over the DNS servers that my current connection handed out over DHCP. I think they came from my school (umn.edu). The two rogue servers are ipv6 ones.
Here is the output if
DNS Servers . . . . . . . . . . . : 2607:ea00:102:2001::53 2607:ea00:102:4001::53 192.168.3.1 NetBIOS over Tcpip. . . . . . . . : Enabled Connection-specific DNS Suffix Search List : umn.edu
Anyone have any thoughts on how to purge these out, or how they came about? They only show up on my wireless connection.
