Basic to Advance Built-in Network Troubleshooting Tools in Windows 7 (and Vista)

networkCommand line tools for Networking are very useful in many ways since Windows 95 and 98. These utilities will help you diagnose network connections.

This tip came from Mr Ed Bott from Microsoft Press book. I’ve just modified and added more information. Thanks for the list!

Arp  Displays and modifies the IP-to-Physical address translation tables used by Address Resolution Protocol (ARP).

Finger Displays information about a user on a specified remote computer or system that is running the Finger service. The output varies on the remote system.

IP Configuration Utility (Ipconfig.exe) Displays all current Transmission Control Protocol/Internet Protocol network configuration values, and refreshes Dynamic Host Configuration Protocol (DHCP) and DNS settings.

Name Server Lookup (Nslookup.exe) Displays information about Domain Name System records for specific IP addresses and host names for troubleshooting DNS problems. Check records, domain host services, domain host aliases, and operating system information by querying DNS servers.

Net services commands (Net.exe) Performs a broad range of network tasks that is use to set, view, access and determine the network settings. Type net with no parameters (or by using net /?) to see the full list of available command-line options.

PathPing (Pathping.exe) Trace a path to a remote system and report packet losses at each router along the way to identify problems at a router or network link.  Basically, It combines the functions of Traceroute and Ping.

TCP/IP NetBIOS Information (Nbtstat.exe) is a command-line tool to troubleshoot NetBIOS name-resolution problems. It Displays statistics for the NetBIOS over TCP/IP (NetBT) protocol, NetBIOS name tables for both the local computer and remote computers, and the NetBIOS name cache.

TCP/IP Ping (Ping.exe) This is a very useful tool that verifies (IP-level) connectivity to another computer or internet address by sending Internet Control Message Protocol (ICMP) packets and measuring response time in milliseconds.

TCP/IP Route (Route.exe) Displays and modifies entries in the local IP routing table.

TCP/IP Traceroute (Tracert.exe) Determines the path to an internet address, and lists the time required to reach each hop. It’s useful for troubleshooting connectivity problems on specific network segments.

To learn more about a specific command line tool including its proper syntax, type the executable name followed by /?.

e.g. ping /?
