  • Test network connectivity and diagnose connection issues with Ping

  • View and manage IP address configurations with IPConfig

  • Flush and manage the DNS resolver cache

  • Diagnose DNS infrastructure problems with NSLookup

  • Trace network routes and identify where connections fail using Tracert

  • View active TCP connections and manipulate routing tables

  • Configure network interfaces and the Windows Firewall with Netsh

  • Identify which routers or subnets are causing network problems

  • Repair corrupted system files with SFC (System File Checker)

  • Service and manage Windows images with DISM

  • Generate power and battery usage reports

  • Check and repair disk problems with CheckDisk

  • View full OS configuration details from the command line
