Applies to: Winfrasoft
X-Forwarded-For for IIS
Problem: The following error
appears when installing or uninstalling X-Forwarded-For for IIS on Windows
Server 2008:
(0x800401e4): Failed to add Filter Winfrasoft
X-Forwarded-For for IIS because Filters node cannot be created.
or
(0x800401e4): Failed to remove Filter Winfrasoft
X-Forwarded-For for IIS because Filters node cannot be read.
Cause: The Winfrasoft
X-Forwarded-For for IIS installation process runs a script to register the ISAPI
filter with IIS. To maintain compatibility with both Windows Server 2003 and
Windows Server 2008 the script is written for IIS6. To allow the script to run
on Windows Server 2008 the IIS 6 Metebase Compatibility Role Service must
be installed and the installation process does not check for this prerequisite.
Except for the ISAPI filter not being registered, the rest of the application
will be installed successfully despite the error.
Resolution:
(1) To resolve the issue add the IIS 6 Metebase Compatibility Role
Service to Windows and re-run the setup. (2) To work around the issue manually
register the ISAPI Filter in IIS7.
Option 1:
In Server Manager select the Web
Server (IIS) Role, add the IIS 6 Metebase Compatibility Role Service to
Windows.
Note: None of the other IIS 6 Management Compatibility options are required.
Re-run the setup for Winfrasoft
X-Forwarded-For for IIS and select the Repair option.
Option 2:
- Open IIS Manager.
- Select the Server name or Web site on which
the X-Forwarded-For for IIS must be registered on.
- Double click ISAPI filters.
- Click Add... in the Actions pane.
- Enter
Winfrasoft X-Forwarded-For for IIS
as the Filter name.
Browse for the XFF4IIS.dll
(32 bit) or XFF4IIS64.dll
(64 bit) file, typically located in the
C:\Program Files\Winfrasoft X-Forwarded-For for IIS\
folder.
Click OK.
- The "Winfrasoft
X-Forwarded-For for IIS" filter is shown in the server/web sites
ISAPI Filters list.
- Stop and Start the web site.
