Get a warning in Endpoint Agent Logs. See below:
Message: Added Only 169.254.86.149 to IP address map. Unable to find domain because: Timed out in DNS reverse lookup query for: 169.254.86.149 Error Code: 1460
Endpoint agents may see slow performance.
Start with restarting the endpoint computer, so it might get a network IP address and not a self-signed IP address.
If this does not work fix the network or network card on the endpoint computer.
