Identification and resolution of TCP/IP problems
Identification and resolution of TCP/IP problems Checking the presence of the TCP/IP layer and IP addresses To find out whether the TCP/IP layer is installed, run the IPCONFIG command from a DOS prompt. A response of this type should be displayed: IP configuration of Windows IP address: 192.168.1.50 Sub-network mask: 255.255.255.0 Default gateway: 192.158.1.220 Where 192.168.1.50 represents an example of a valid IP address. If an error message is displayed or if the IP address is 0.0.0.0, then no TCP/IP layer is installed on the computer. Install the network layer (in the Windows control panel, double-click "Network" and "Add/Protocol"). Checking the configuration of the TCP/IP layer To check whether the TCP/IP layer is installed and configured properly, you must perform a 'ping' on the loop address (127.0.0.1). To do so, run the PING command (127.0.0.1) from a DOS prompt. A response of this type should be displayed: Sending a 'ping' request on 127.0.0.1 with 32 bytes of data: Reply from 127.0.0.1: bytes=32 time<10ms TTL=128 Reply from 127.0.0.1: bytes=32 time<10ms TTL=128 Reply from 127.0.0.1: bytes=32 time<10ms TTL=128 Reply from 127.0.0.1: bytes=32 time<10ms TTL=128 If an error message is displayed, then the TCP/IP layer was not installed properly on this computer. Install the network layer (in the Windows control panel, double-click "Network" and "Add/Protocol").
