How to fix Micro$oft Server running IIS and it grabbing all of the ports (e.g., 80, 443, etc.)

What goes wrong?                             

When you try to run Office-Logic InterChange on the same box that you use for web services, e.g., IIS or some of the virus scanner definition servers, etc. You will probably run into problems with the port numbers being unavailable or the services not starting.

What's the problem?                             

For example when you run Office-Logic InterChange, you see a message that shows "Unable to bind to port 80. Already in use." By default, IIS and InterChange listen to all IP addresses on the box. You can tell the service to only listen to the IP address you specify. Even though you specify the IP address for IIS to listen, it will still tie up the ports on the other IP addresses. nected to the LAN. In fact it did not free up the NIC that is connected to the Internet. Thus when you try to use that NIC for ISA Server, ISA Server will tell you that the SMTP port (25) on the Internet NIC is already in use by another application.
