So I have a problem. We are changing internal DNS servers (retiring old AD DCs), so I wrote a script in Powershell that reads the current DNS using a WMI call, then sets the DNS servers using the returned method. This works fine ... except I inadvertently ran it against 1 node of a MS 2008 R2 cluster.
Now, in addition to the teamed NIC having the proper DNS settings, the "Microsoft Failover Cluster Virtual Adapter" also has these same DNS settings. And I don't think it is supposed to ... On the other node, the virtual adapter looks like it is listing 3 IPv6 addresses: fec0:0:0:ffff::1%1 fec0:0:0:ffff::2%1 fec0:0:0:ffff::3%1 the problem, of course, is that there is no way to edit that virtual adapter (except perhaps in the way I did, using a script). If I searched correctly, those IPv6 addresses don't really point to anywhere (we don't use IPv6, and none of my DNS servers have it enabled, anyway) So: what have I done? Will this break anything? I can't see how, as neither virtual adapter has a gateway defined at all. if I have to fix it ... how? anyone?
