To determine why a TCP/IP connection to a remote computer is not working properly
· Use the netstat -a command to show the status of all activity on TCP and UDP ports on the local computer.
The state of a good TCP connection is usually established with 0 bytes in the send and receive queues. If data is blocked in either queue or if the state is irregular, there is probably a problem with the connection. If not, you are probably experiencing network or application delay.
