boost asio fail to bind port 80

Question

My application is written in c++ thanks to boost asio library, with classical methods:

acceptor_.open(endpoint.protocol());
acceptor_.set_option(boost::asio::ip::tcp::no_delay(true));
acceptor_.set_option(boost::asio::ip::tcp::acceptor::reuse_address(true));
acceptor_.bind(endpoint);
acceptor_.listen();

On same machine, iis is running for a classic website.

I can't bind endpoint on port 80 in same time website is running. When i put a other port for binding, all is ok. It would be Is there an issue for usin website and asio binding on same port?

Thanks for help me ...

Answer 1

IIS binds to port 80 by default. so that you cannot bind. If you want to bnd to port 80, stop IIS.
