The information in this article applies to:
- Microsoft Internet Information Services version 6.0
Important This article contains information about editing the metabase. Before you edit the metabase, verify that you have a backup copy that you can restore if a problem occurs. For information about how to do this, see the "Configuration Backup/Restore" Help topic in Microsoft Management Console (MMC).
SYMPTOMS When Microsoft Internet Information Services (IIS) receives a GET request without a host header, the Web server may reveal the IP address of the server in the content-location field or the location field in the TCP header in the response. This problem may occur if the request does not contain a specific page or if IIS must redirect the original request to another page.CAUSEThis problem occurs because when IIS receives a GET request that has no host header, IIS must provide a host name or an IP address in the response.RESOLUTIONHotfix informationA supported hotfix is now available from Microsoft, but it is only intended to correct the problem that is described in this article.

10-Dec-2003 18:07 6.0.3790.91 299,008 W3core.dll STATUSMicrosoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.MORE INFORMATIONWarning If you edit the metabase incorrectly, you can cause serious problems that may require you to reinstall any product that uses the metabase. Microsoft cannot guarantee that problems that result if you incorrectly edit the metabase can be solved. Edit the metabase at your own risk. Note Always back up the metabase before you edit it.
After you apply this hotfix, you must set either the UseHostName property or the SetHostName property on the site if you want an alternate host name to be sent for requests. By default, the same value as the HTTP_HOST variable is sent in the SERVER_NAME variable. Note If you enable one the following settings, IIS will always use an alternate name for the SERVER_NAME variable. The data type for the UseHostName property is Boolean. The UseHostName property will instruct IIS to always replace the SERVER_NAME variable with the fully qualified machine name. Optionally, you can set the SetHostName property. The data type for the SetHostName property is string. Use the SetHostName property if you must specify a host name that is different from the computer name. The SetHostName property assumes that you want this alternate host name. The SetHostName property will cause IIS to ignore the UseHostName setting. You do not have to set the UseHostName property if the SetHostName property is present.
A Web server administrator may use the Adsutil.vbs tool to modify the UseHostName metabase property and the SetHostName metabase property. To set the UseHostName property, follow these steps: - Click Start, click Run, type cmd, and then click OK to open a command prompt.
- Change to the folder where the Adsutil.vbs tool is located. By default, this folder is the following:
%SYSTEMROOT%\Inetpub\AdminScripts - Type the following command, where x is your site identifier:
cscript adsutil.vbs set w3svc/x/UseHostName
true
To set the SetHostName property, follow these steps: - Click Start, click Run, type cmd, and then click OK to open a command prompt.
- Change to the folder where the Adsutil.vbs tool is located. By default, this folder is the following:
%SYSTEMROOT%\Inetpub\AdminScripts - Type the following command, where x is your site identifier and hostname is the alternate host name that you want to use:
cscript
adsutil.vbs set w3svc/x/SetHostName hostname
