The Microsoft Exchange Server Best Practices Analyzer examines the Internet Information Services (IIS) components that are installed on an Exchange server to determine whether the Active Server Pages component is installed.

If the Analyzer detects that Active Server Pages is not installed, the tool generates a warning message. To use the Change Password functionality in Microsoft Office Outlook Web Access, Active Server Pages must be installed.

You can configure Outlook Web Access to let users change their domain passwords. To enable Outlook Web Access to let users change passwords that have already expired, you must create the IISADMPWD virtual directory in IIS.

When a user who has an expired password logs on to Outlook Web Access, the user is automatically redirected to the IISADMPWD virtual directory and prompted to change his or her password. The IISADMPWD virtual directory requires Active Server Pages to load the ASP Web page for the password change functionality. If Active Server Pages is not installed, users receive the following error when they try to change passwords:

HTTP Error 404 - Page not found.

Therefore, the users cannot change their passwords or log on to Outlook Web Access.

To address this issue, install Active Server Pages on the servers that host Outlook Web Access.
