Error "only one usage of each socket address is normally permitted"

Now this error is disturbing me whenever i am trying reusing a socket. It says,"only one usage of each socket address is normally permitted". The message occurs on a win2k server with sp3. I cannot spot what is causing the problem.Can anyone give me some instructions or an example on how to correctly close a socket so its resources (port) can be used for other sockets ?

This problem occurs during CM Server installation when anti-virus tools or remote connection software such as PC Anywhere are enabled. You may have either two different apps trying to open orcontrol the same port(socket) address.

So before running any programs make sure that ports are free. To do this open your command prompt and type netstat /a. This command list all active connections on the system.

Most probably this error occurs when multiple instances of the same application trying to use the same socket at the same time. So you need to get which program is running on the port listed in the error message. netstat -a can do that. Once the program is identified, hold it against before another new beginning of RWP or installation of the Server to attempt cm. If the program that the port currently used can not be stopped, you will find the instructions for your appropriate product version must follow the standard HTTP port change.

Thanks, I was unaware that these options had netstat. By the time I read your suggestion, was already working. I can not account except that it was closing laptop and started file. There were some pending security updates and reboot requirements when it started I was not that message when I set my program in operation.
