1. Common Problems
a. Lack of Internet Connectivity
Description: The system cannot access the internet, affecting browsing, downloads, or updates. Symptoms: DNS resolution fails, ping to external IP (e.g., 8.8.8.8) fails. Real-Life Example: A company’s firewall blocks outbound HTTPS due to expired rules after a policy update.
b. Resource Unavailable
Description: Cannot reach shared folders, applications, or intranet services. Use Case: An employee tries to access a network printer or NAS, but receives "resource not found" or timeout errors.
c. Receiving Incorrect DHCP Information
Description: The client receives a wrong IP, gateway, or DNS server. Real-Life Example: A rogue DHCP server on the guest VLAN assigns incorrect DNS, breaking domain authentication.
d. Non-Functional or Unreachable
Description: Host does not respond to pings or is marked offline. Cause Example: Device may be powered off, disconnected, or has a misconfigured IP.
