Although it is not primarily a troubleshooting tool, Telnet Client is extremely useful for determining whether TCP-based network services are reachable from a client . Most commonly used network services are TCP based, including Web services, mail services, and file transfer services . Telnet Client is not useful for troubleshooting UDP-based network services such as DNS and many streaming media communications . Telnet Client is not installed by default in Windows 7 . To install it, run the following command from a command prompt with administrative privileges .

CHapTER 31 Troubleshooting Network Issues
Telnet Client is useful only for determining whether a service is reachable, and it will not provide information that you can use for troubleshooting name resolution, network performance, or network connectivity problems . Use Telnet Client only after you have used Ping to eliminate the possibility of name resolution problems . For more information about Ping, see the section titled Ping earlier in this chapter .
Testing Service Connectivity
After you have identified the port number for the service, you can use Telnet Client to test connectivity to that service . To test connectivity to a service, open a command prompt and run the following command .
telnet destination portnumber
For example, to test HTTP connectivity to www.microsoft.com, type the following command at the command line .
telnet www.microsoft.com 80
The destination might be a host name, computer name, or IP address . The response you receive will indicate whether a connection was established . If you receive the message Could not open connection to the host, the host did not respond to the request for a connection on the port number you specified, and the service you are testing is unreachable . If you receive any other response, including all text disappearing from the command window, the connection was successfully established . This eliminates the possibility that the problem you are troubleshooting is caused by a connectivity issue between the client and the server . Depending on the service you are testing, Telnet Client can be automatically disconnected, or the session might remain open . Either circumstance indicates a successful connection . If the Telnet Client session remains open, you should disconnect Telnet Client to close the connection . To disconnect Telnet Client, follow these steps:
1. 2.
Press Ctrl+] . When the Microsoft Telnet> prompt appears, type quit .
Test TCp
With Test TCP, you can both initiate TCP connections and listen for TCP connections . You can also use the Test TCP tool for UDP traffic . With Test TCP, you can configure a computer to listen on a specific TCP or UDP port without having to install the application or service on the computer . This allows you to test network connectivity for specific traffic before the services are in place . Test TCP (Ttcp .exe) is a tool that you can use to listen for and send TCP segment data or UDP messages between two nodes . Ttcp .exe is provided with Windows Server 2003 in the Valueadd\Msft\Net\Tools folder of the Windows Server 2003 or Windows XP Service Pack 2 (SP2) product CD-ROM .

Test TCP differs from Port Query in the following ways:
With Test TCP, you can configure a computer to listen on a specific TCP or UDP port without having to install the application or service on the computer . This allows you to test network connectivity for specific traffic before the services are in place . For example, you could use Test TCP to test for domain replication traffic to a computer before you make the computer a domain controller . Test TCP also supports IPv6 traffic .
When you are using a TCP port, the following code shows the basic syntax for Ttcp .exe on the listening node (the receiver):
