Windows Server 2016 DNS issue for Windows 10 client PCs

Last Modified: 2021-04-12
I have a client with a server 2016 domain looking after 15 machines and 2 hyper v machines all running Win 10.  The server is mainly acting as a file/printer share and one 3rd Party program running SQL. Emails are on Exchange Online.

The problem I am having is every day the client PC's loose connection to the server, cannot browse the internet and outlook cannot connect to Microsoft Exchange.  I can still connect to all the machines remotely via RDP, ISLOnline or Teamviewer etc, but internet browsing or connection to the server/exchange is not possible.

I suspect it is some sort of DNS/DHCP error.
I have tried restarting DHCP and DNS services to no avail.  The only thing that corrects this problem is a server restart.  Restarting the server will get the machines going for approx a day or a bit longer.  I have check all event logs on the server and the only Errors that are being generated are at the time I am restarting the server.

Each client machine has a static IP address and DNS settings set as Server and Google dns for backup
I have attached screen shot of Server IP settings and DNS setup, along with IPCONFIG of one of the client machines.
I am having to restart the server every morning before staff arrive to ensure there are no problems that day, but I need a more permenant solutioon.  Any advice would be greatly appreciated.



I now restart the server every morning to ensure smooth operation that day but I need to find a permenant solution.
