IIS Binds To All Available IP Addresses When It Starts

SYMPTOMS

When you start Internet Information Services (IIS) 5.0, IIS appears to bind to all Internet Protocol (IP) addresses on a server, not just the IP addresses that are assigned to Web sites. In addition, when you run another service that uses port 80 on an unused IP address, IIS may return an error.

CAUSE

To enhance performance, IIS 5.0 uses "socket pooling", in which IIS binds to all IP addresses when it starts.

WORKAROUND

To work around this behavior, disable socket pooling in IIS as follows:

At a command prompt, switch to the "C:\InetPub\AdminScripts" folder.
Type the following command:
CSCRIPT ADSUTIL.VBS SET W3SVC/DisableSocketPooling TRUE
