If you set up Microsoft Outlook Web Access (OWA) in a Web site outside the default Web site in Exchange 2000, and then try to use OWA to change the password, you may receive the following error message:
Additionally, the following is logged in the IIS 6.0 log:
The page cannot be found
HTTP 404 - File not found
Internet Information Services
<Time> <IP Address> GET /<PageName> 404
This issue occurs because OWA uses the Davex.dll file or Exprox.dll file (the Exprox.dll file for front-end servers and the Davex.dll file for back-end servers) to intercept requests to that Web site and process those requests for OWA.
By default, if you create a virtual directory (such as IISADMPWD) under a Web site, that virtual directory inherits properties from the parent. One of the properties that the virtual directory inherits is the list of extensions. The list of extensions includes the Davex.dll or Exprox.dll file, depending on whether the server is a back-end server or a front-end server.
When a user tries to gain access to the Password Change page (Aexp2b.htr) under the IISADMPWD virtual directory, either the Davex.dll file or the Exprox.dll file intercepts the request, which generates an HTTP 404 error message.
