are you using DHCP on your environment?

169 range is auto assigned by MS if it cannot attain IP address via DHCP.

As I can see on this PC, the DHCP is not enabled.

If you are using static IP address, you might have an IP address duplication.

Is someone on your network configured with a Static Address that is conflicting. I have seen that happen.

In my case, a workstation was reporting a duplicate IP and the user reported it, so it was easy to determine the problem area.

Run TCP/IP reset to see if that changes anything.

To manually reset:  Open cmd.exe with Run as Administrator:  netsh int ip reset c:\resetlog.txt

Also, for DNS, ipconfig /flushdns, then net stop dnscache followed by net start dnscache

The image shows that DHCP is off so that would be a static IP address.

Try changing your static IP configuration to an available IP or enable dhcp if you have dhcp on your environment

To find the other host you can disconnect the machine with the screenshot and use another machine in the same subnet to ping the ip.
If it still answers, use (win)arp -a / (lin) sudo arp -n to get the mac-address.

It is an IP address conflict. Just disbale the interface and try to ping to 172.16.27.145. You'll get ping response from another host. To check the host name do ping -a 172.16.27.145.
