Hi Mohammed_f
Please let us know the below:
==> Does the PC getting the IP address and dns settings from the DHCP server ?
==> Does fortigate acts as DHCP server in your network ?
==> Does all the users are facing the issue or a group of user?

The pc get ips from the dhcp Server
The fortigate act as gatway and only firewall not dhcp Server

You need to ensure your DHCP server is assigning the correct DNS servers to your clients. Please check your DHCP server configuration.
