port not listening..

Hi..
I am using HPux11.0
i want to know if server not listening to a tcp port what should we do to resolve the problem....

in /etc/services tcp port 7108/tcp is mentioned for some perticular application..
while starting that application error is coming could not establish
listening address on network //uswest02:7108

uswest02 is the hostname..

please suggest where should i start to solve this problem..
thanks

Ports don't listen, processes listen. The /etc/services file des not specify running processes. /etc/services is just a table of the mapping of names to numbers and exists as a convienence, not as a requirement for networking.
