The information in this article applies to:

- Microsoft Internet Information Services version 5.0 
-------------------------------------------------------------------------------

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:

1. At a command prompt, switch to the "C:\InetPub\AdminScripts" folder.

2. Type the following command:

  " CSCRIPT ADSUTIL.VBS SET W3SVC/DisableSocketPooling TRUE " (without the
  quotation marks)
