How do I troubleshoot a 'Error 1001' DNS resolution error on GoDaddy?

To troubleshoot, first, verify your DNS records within GoDaddy's DNS management panel. Ensure they are accurate and point to the correct server. Second, check your domain registrar's nameservers – ensure they are correctly configured with the ones provided by GoDaddy. Third, clear your local DNS cache on your computer and router. Finally, wait up to 48-72 hours for DNS propagation, as changes can take time to spread across the internet.
