A small business has a single server running Windows Server 2019 that acts as a domain controller, file server, and DHCP server. The server has a single network interface with IP address 192.168.1.10/24. The office has 30 client computers running Windows 10. All clients obtain IP addresses automatically. The network uses a single unmanaged switch. The internet connection is provided by a cable modem with IP 192.168.1.1. The server is configured with a static IP of 192.168.1.10, and the DHCP scope is 192.168.1.100-192.168.1.200. Recently, users have reported that they cannot access the internet.
