DNS records keep coming back....
Posted on 2007-10-01
We have a small network with DC's in each branch office. Each server has two NIC's, however, the second NIC has been set not to register it's IP in DNS. We use the second NIC to monitor netwrok traffic off of a mirrored switch port only. The problem is that on each server after about 10 minutes, the DNS record for the second NIC appears and is casusing resolution issues. This happens on both servers. The second NIC only has an IP address and a subnet address...no gateway or DNS is assigned. When I run ipconfig /registerdns, the records are delted, but then reappear a few minutes later. I've searched all over for this behavior, but have not been able to find any resolution. The record reappear on both the xyz.local zone and the _msdcs.xyz.local zone.
