1. Check the hosts file: The first step to troubleshoot DNS resolution issues is to check the hosts file. This file contains mappings between domain names and IP addresses that are used by the operating system without consulting DNS servers. If a domain name is present in the hosts file and its IP address is incorrect or outdated, this could prevent successful resolution of the domain name.
2. Check the DNS settings: Another step to troubleshoot DNS resolution issues is to check the DNS settings of the computer. Make sure the DNS server addresses set in the network configuration match up with the ones provided by the ISP. Also, verify that the DNS server is running properly by pinging it.
