The procedure given below will help you to reconfigure HTTP. For more information refer the article "Running ISA Server on Windows Server 2003", link given below.

This is a general procedure to configure port binding of HTTP , but this example is related with ISA.

When you run ISA Server 2000 and Microsoft Internet Information Services 6.0 (IIS) on the same computer, you may experience issues with the ISA Server Web proxy service (W3proxy). By default, IIS listens on all IP addresses. This prevents W3proxy from binding to port 80 for Web publishing. To resolve this issue, follow these steps: 

1. Install the Windows Server 2003 Support Tools (included with Windows Server 2003), and then locate the Httpcfg.exe file.
2. Run the Httpcfg.exe utility to configure HTTP.sys to stop listening on all IP addresses. To do this, type httpcfg delete iplisten -i 0.0.0.0 at a command prompt.
3. Configure HTTP.sys to listen only on the specified IP address (usually the internal IP address of ISA Server) by typing httpcfg set iplisten -i ip-address at a command prompt.
4. Stop the IIS HTTP service by typing net stop http at a command prompt.
5. Stop the ISA Server Web proxy service by typing net stop w3proxy at a command prompt.
6. Restart the IIS HTTP service by typing net start http at a command prompt.
7. Restart any related IIS services. For example, type net start "World Wide Web Publishing Service".
8. Restart the ISA Server Web proxy service by typing net start w3proxy at a command prompt."
