We have a Windows 8.1 Pro domain attached workstation that has been experiencing frequent DNS related errors. Several times per day the end user's MS Outlook 2016 will go offline and show 'disconnected' in lower right corner. A reboot, temporarily disabling IPv6, or connecting to the WiFi network (instead of ethernet) generally solves the issue for a short time and then it happens again. Also, when trying to access the OWA mail app in Chrome I received this error - "outlook.office365.com's server DNS address could not be found"
Please note that the domain controller is running Windows Server 2012 and has DHCP and DNS roles running and other domain connected workstations are working as expected. Any suggested troubleshooting steps will be most appreciated.
