On a computer that is running Windows 8 or Windows Server 2012, non-English site names are not displayed in the "s-sitename" field in an Internet Information Services (IIS) log file.

For example, consider the following scenario:
  • You create a site by using multibyte, non-English characters.
  • In the Applicationhost.config file, you set the site "logSiteId" setting to "false." For example, the configuration in the Applicationhost.config file resembles the following:
    <site name="site name" id="2"> 
    <application path="/" applicationPool="site name">
    <virtualDirectory path="/" physicalPath="C:\inetpub\wwwroot" />
    <binding protocol="http" bindingInformation="*:8080:" />
    <logFile logSiteId="false" />
  • You send an HTTP request to the site.
  • You open an IIS log file to view the "s-sitename" field.
In this scenario, the site name is an unrecognizable string.


This issue occurs because the Http.sys file cannot handle non-English site names. The Http.sys file is given a Char string instead of a WCHAR string.
