We have a windows 2003 file server that used to be a Domain controller.
We demoted it from being a DC to just a fileserver few months back. I have just noticed that in the event log, I am getting the following error.
This server has to NICs. I noticed that both cards had thier secondary DNS server point to the one of the NIC's on itself ( the same server). But, the primary DNS was fine and was pointing to the right DC.
I also ran netdiag /fix and I think it looked fine. I now took the secondary DNS out and changed it to a secondary dns.
