Troubleshooting can be difficult if you don’t have the right tools. Luckily Microsoft provided some very useful command prompt tools in Windows Server to help you troubleshoot network problems.
- Arp — Displays the Address Resolution Protocol (ARP) cache, and adds and removes MAC addresses from the cache.
- Hostname — Displays the hostname of the local computer.
- Ipconfig — Displays the TCP/IP configuration, renews the DHCP lease, purges the DNS cache, etc.
- Nbtstat — Displays the statistics and connections of NetBIOS over TCP/IP (NBT) and troubleshoots NetBIOS name resolution problems.
- Netstat — Displays the statistics for current TCP/IP connections.
- Netdiag — Performs some simple network tests.
- Network Monitor — Captures and displays all packets on the network.
- Nslookup — Troubleshoots the DNS.
- Pathping — Route-tracing tool that combines the features of ping and tracert.
- Ping — Sends ECHO packets to verify that TCP/IP is configured and that remote systems are available.
- Route — Displays the IP routing table and adds and deletes IP routes.
- Tracert — Traces a route to remote systems.
Some additional tools can be found in the Windows Server Resource Kit:
- Netset — Configures a variety of network parameters from the command line.
- Getmac — Displays the physical MAC address of network cards.
- Wntipcfg — Serves as a GUI version of the command line’s Ipconfig.
