DOCUMENT:Q259349 22-DEC-2000 [iis] TITLE :IIS Binds To All Available IP Addresses When It Starts PRODUCT :Internet Information Server PROD/VER::5.0 OPER/SYS: KEYWORDS:kbOSWin2000 kbDSupport kbiis500 ====================================================================== ------------------------------------------------------------------------------- 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) MORE INFORMATION ================ For additional information, click the article number below to view the article in the Microsoft Knowledge Base: Q238131 How to Disable Socket Pooling Additional query words: ====================================================================== Keywords : kbOSWin2000 kbDSupport kbiis500 Technology : kbiisSearch kbiis500 Version : :5.0 Issue type : kbprb Solution Type : kbpending ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
