Have you already checked (through netstat or similar) that the configured ports were not bound before launching the Server?

It could be a system-level limitation.
For instance, in unix/linux a user other than root cannot open a port lower than 1024 in listening.
Your case is worse, as you could not open even higher ports.
Lightstreamer opens the configured ports for listening in a standard way,
so, it should not suffer from limitations that don't apply also to other programs.

thanks for your valuable reply, i have check the active connection using netstat
result pasted below. 8080 port is not using, i am using Winxp, is there any solutions to properly configure the port and run the lightstreamer server in local, if i want to install in another pc then what steps i need to follow to run the tool.

Need to disconnect [stop] IIS, cause IIS uses port 80
now the lightstreamer server is running in my local on port 80

[Ooops, I probably missed your previous post; I leave the following comment anyway].

Just in case, please, make sure you are including listening ports in the "netstat" inquiry (see netstat -?).

All the steps needed to run Lightstreamer are those shown in GETTING_STARTED.TXT
Obviously, the availability of a few ports for opening in listening mode is a precondition.
Is it possible that a firewall in the local machine is configured in order to forbid opening of any port in listening? Note that Lightstreamer does not negotiate its ports with firewalls, so you should make the needed ports available by acting on the firewall configuration manually.
