Problem activating an Inbound HTTP Port

I am creating a new integration port for my web service using HTTP adapter in AX 2012. During the procees we need to select a default web site which is present in ax. In my system there was no default web site present so i started creating a web site.

System administration> Setup> Services and Application Integration Framework> Web sites. This is the path to create a web site. Web site was sucessfully created.

Now i selected this web site as my default web site. I added the service operations to my integration port. Now when i activated the port is gives an error stating

 " The port 'My port name' could not be deployed.\nError: The deployment web site was not found for port: My port name"

What should i do?

Any help with help a lot.

Thanks in advance
