FP2000: Error Message: Error INI File Section Port 80 Not Found

When you attempt to open a subweb after upgrading to the Microsoft FrontPage 2000 Server Extensions, you may receive the following error message: The subweb does not open as expected.

This behavior can occur if there is a physical _vti_bin folder in the subweb rather than a virtual _vti_bin directory. To verify this, use Windows Explorer to examine the folders in your Web content area and look for a _vti_bin folder.

To resolve this issue, use the appropriate method for your version of IIS:

If you are using IIS 4.0

1. Make sure that the FrontPage Server Extensions are not currently loaded into memory. To do this, restart Internet Information Services (IIS). To do this, use either of the following methods:
   • Restart the WWW, FTP, and IIS Admin Services by using the Services Control Panel.
     
     -or-
   • Restart all of the IIS services by using a batch file. For additional information, click the article number below to view the article in the Microsoft Knowledge Base:

In FrontPage 98 and earlier, the FrontPage extensions were physically installed to folders that contained FrontPage Webs. In contrast, in FrontPage 2000, all FrontPage Webs share the same executables by adding a virtual folder to each Web that points to the location of the FrontPage common files. In some situations, the physical folder still exists and prevents the FrontPage extensions from functioning correctly.
