Windows 2012 server environment. Windows 10 Pro client.
Had a user that could not get on the internet so I went to command line and did ipconfig /all and noticed that the DNS server was 192.168.1.1 The settings for this computer were obtain ip and Dns auto. I changed it to 188.8.131.52 and all is well. I will change back to auto later and see what happens. Any reason how this could have been changed when it was set to auto?
NOTE: When I looked at ipv4 in the LAN properties both the ip address and DNS WERE set to auto.
