Do you feel annoying of many network problems when you surf the internet and you have no ideas to solve them? Fortunately, Windows 7 provides a series of utilities you can use to monitor, diagnose, and repair network connections. Now I will show you some of the more useful networking-related command-line utilities in Windows 7 and a summary of how to use them. In order to learn more about a utility, including its proper syntax, in a Command Prompt window type the executable name followed by /?.

TCP/IP Ping (Ping.exe) Verifies IP-level connectivity to another internet address by sending Internet Control Message Protocol (ICMP) packets and measuring response time in milliseconds.

PathPing (Pathping.exe) Combines the functions of Traceroute and Ping to identify problems at a router or network link.

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

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.

Net services commands (Net.exe) Performs a broad range of network tasks. Type net with no parameters to see a full list of available command-line options.

Netstat (Netstat.exe) Displays active TCP connections, ports on which the computer is listening, Ethernet statistics, the IP routing table, and IPv4/IPv6 statistics.

Network Command Shell (Netsh.exe) Displays or modifies the network configuration of a local or remote computer that is currently running. This command-line scripting utility has a huge number of options, which are fully detailed in Help.

Get MAC Address (Getmac.exe) Discovers the Media Access Control (MAC) address and lists associated network protocols for all network cards in a computer, either locally or across a network.

Name Server Lookup (Nslookup.exe) Displays information about Domain Name System records for specific IP addresses and/or host names so that you can troubleshoot DNS problems.

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

Hostname (Hostname.exe) Displays the host name of the current computer. Additional Except the utilities that I mentioned above, there is aslo a very powerful and handy tool worth mentioning that is not available in Windows 7 but is available as a free download. Network Monitor is a protocol analyzer that lets you capture network traffic, view it, and analyze it.
