Window Server - Binding Web Interface to port 80 when IIS is running
By default IIS listens on all IP addresses on port 80, assigned to a PC. So what needs to be done is to configure IIS to listen only on one IP address. Follow
the steps described below, depending on what operating system is running on the server:
Window Server 2003
Go to Administrative Tools->Internet Information Services, and then to "server name"->Web sites->Default Web site, right-click, properties, go to the 'Web
Site' tab, and in 'Web Site Identification' put the IP address you want IIS to bind to or click the 'Advanced' button to select more than one IP.
Then disable 'Socket Pooling' by following the next steps:
1. Open a command prompt and make sure you are in the X:\Inetpub\Adminscripts folder (where X is the IIS installation drive).
2. After you open the Adminscripts folder, type the following line at the command prompt:
cscript adsutil.vbs set w3svc/disablesocketpooling true
The command replies: disablesocketpooling : (BOOLEAN) True
3. Stop and start the IIS Admin and depending services.
Window Server 2008
Run this command from the command port:
netsh http add iplisten ipaddress=IPADDRESS (replace IPADDRESS with the IP to bind)
