Frequently asked questions about Fpexedll.dll

What is Fpexedll.dll?

The Fpexedll.dll file is installed with the FrontPage Server Extensions on Microsoft Internet Information Services (IIS) to provide backward compatibility with Microsoft FrontPage for Windows, version 1.1, and Microsoft FrontPage for the Macintosh, version 1.0.

When authoring on an IIS-based Web server, FrontPage versions 1.0 and 1.1 make requests for the older CGI-based Server Extension files (Shtml.exe, Author.exe, and Admin.exe) rather than the newer ISAPI-based files (Shtml.dll, Author.dll, and Admin.dll) as they are known in FrontPage 97 and later. The Fpexedll.dll filter examines every HTTP request coming into the system and, if a request is for one of the CGI-based executable files, the Fpexedll.dll filter converts the URL so that the corresponding ISAPI-based dynamic-link library (.dll) file is called.

Do I need to use Fpexedll.dll?

The Fpexedll.dll ISAPI filter only provides backward-compatibility with FrontPage versions 1.0 and 1.1. If you are not using these versions of FrontPage, you do not need to use this filter. You can safely remove any references to the filter from your IIS configuration.

Note There is no need to physically delete the DLL file from your hard disk.

When should I remove IIS references to Fpexedll.dll?

• If there are two references to the Fpexedll.dll file listed in your IIS configuration, remove one of them. The remaining reference should point to the correct location of Fpexedll.dll, depending on which version of the FrontPage Server Extensions is installed.
• If there is only one reference to Fpexedll.dll, make sure that no clients are authoring against the server using either FrontPage 1.0 or FrontPage 1.1. If there are no such clients, you can remove the reference to Fpexedll.dll. It serves no functional purpose and could theoretically slow requests that are processed by IIS.

Note There is no need to physically delete the DLL file from your hard disk.
