We strongly recommend that all users upgrade to Microsoft Internet Information Services (IIS) version 7.0 running on Microsoft Windows Server 2008. IIS 7.0 significantly increases Web infrastructure security. For more information about IIS security-related topics, visit the following Microsoft Web site: (

When you attempt to change a password in Outlook Web Access (OWA) or browse one of the .htr files directly, or if you try to execute a Common Gateway Interface (CGI), Internet Server Application Programming Interface (ISAPI), or other executable program from a directory that does not allow programs to be executed, you may receive the following error message in the Web browser:
HTTP Error 403

403.1 Forbidden: Execute Access Forbidden


The Iisadmpwd virtual directory in the Internet Service Manager does not have script permissions.


To resolve this problem, follow these steps:
  1. Open the Internet Service Manager Microsoft Management Console (MMC).
  2. Right-click the Iisadmpwd virtual directory and then click Properties.
  3. On the Virtual Directory tab, change the permissions from none to script.
NOTE: By default, IISADMPWD is installed as a physical folder under Microsoft Windows 2000, but not as a virtual directory under Internet Information Services (IIS) version 5.0. Because of this, IIS does not recognize that the directory exists. If the problem persists, contact the administrator of the Web server.


IIS 4.0 includes the capability that allows a Microsoft Windows NT 4.0 user to change passwords and to receive notification when a password is about to expire. IIS installs this functionality in the IISADMPWD virtual directory of the default Web site. This feature is implemented as a set of .htr files that are located in the %system%\System32\Inetsrv\Iisadmpwd directory and the ISAPI Ism.dll extension file.

For more information about how to configure IIS to support password changes, view the "Notifying Clients of Password Status" topic in the Windows NT 4.0 Option Pack documentation.
