SUMMARY

The Password Change pages that are included with Microsoft Internet Information Services (IIS) 6.0 on a Microsoft Windows Server 2003 system have multiple problems. You can resolve these problems by installing the hotfix that is described in this article.

SYMPTOMS

You may experience the following problems with the Password Change pages that are included with Microsoft Internet Information Services (IIS) 6.0:
  • The first letter of the user's account name is truncated.
  • The domain name is not correctly populated.
  • You cannot change passwords for users whose passwords must be changed at the next logon.
  • You cannot change passwords for users whose passwords have expired.
  • You cannot change passwords across forests.
  • You cannot use user names in the UPN format.

CAUSE

Most of the problems that are associated with the Change Password pages occur because of the technological limitations of Active Directory Service Interfaces (ADSI) when ADSI is used in an Active Server Pages (ASP) page on a Web site.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

MORE INFORMATION

Warning If you edit the metabase incorrectly, you can cause serious problems that may require you to reinstall any product that uses the metabase. Microsoft cannot guarantee that problems that result if you incorrectly edit the metabase can be solved. Edit the metabase at your own risk.

Note Always back up the metabase before you edit it.

After you apply this hotfix, follow these steps to configure the Password Change functionality:
  1. 1. Apply the hotfix to update the files on the computer that is running IIS or install service pack 1 for Windows 2003. The hotfix will automatically register the module and you can proceed to step 3. If Service Pack 1 has been installed without the hotfix, you must manually register the module.
  2. Register the IISpwchg.dll file in the Iisadmpwd directory:
    1. Click Start, and then click Run.
    2. In the Open box, type the following, and then press ENTER:

      regsvr32 c:\windows\system32\inetsrv\iisadmpwd\iispwchg.dll

  3. Configure the PasswordChangeFlags property in the metabase to make sure that the Password Change functionality is enabled:
    1. Click Start, and then click Run.
    2. In the Open box, type cmd, and then press ENTER.
    3. Locate the C:\Inetpub\Adminscripts directory.
    4. Type the following command, and then press ENTER:

      cscript.exe adsutil.vbs set w3svc/passwordchangeflags Value

      Note In this sample command, Value is a placeholder for the value that you want to set for the PasswordChangeFlags property.
  4. The following list includes the possible values for the PasswordChangeFlags property. You can use a combination of these values.
    • 0: This is the default value. This value indicates that you must use a Secure Sockets Layer (SSL) connection when you change the password.
    • 1: This value permits password changes on non-secure ports. This value is useful if SSL is not enabled.
    • 2: This value disables the Password Change functionality.
    • 4: This value disables the advance notification of password expiration.
  5. Make sure that the virtual directory for the Iisadmpwd directory is correctly created and that it points to the correct location. The correct location is System32\Inetsrv\Iisadmpwd.

    To create a virtual directory for the Iisadmpwd directory, follow these steps:
    1. Click Start, click Programs, click Administrative Tools, and then click Internet Information Services (IIS) Manager.
    2. In Internet Information Services (IIS) Manager, right-click the Web site where you want the Iisadmpwd folder, click New, and then click Virtual Directory.
    3. When the Virtual Directory Creation Wizard starts, follow the instructions to create the virtual directory with the alias that is named "IISADMPWD." Make sure that the path points to the Windows\System32\Inetsrv\Iisadmpwd directory. Make sure that both "Read" permissions and "Run Scripts (such as ASP)" permissions are selected.
  6. Make sure that the Iisadmpwd virtual directory runs in the same application pool as the Web site that uses the Password Change functionality. For example, if the Password Change functionality is used in your Microsoft Outlook Web Access (OWA) Web site, the Iisadmpwd virtual directory must run inside the Exchange application pool where the OWA site resides.

    Note We recommend that the authentication for IISADMPWD is the same as the application that is using this functionality. Anonymous Authentication is not required to be enabled on this virtual directory.
  7. Verify that the following metabase entries are set correctly:
    Metabase entry and valueDescription
    AuthChangeURL = "/iisadmpwd/achg.asp"This page does the actual password change work.
    AuthExpiredURL = "/iisadmpwd/aexp.asp"This page displays the password change form for a user whose password has expired. Make sure that you type the account name in the "domain\username" format.
    AuthExpiredUnsecureURL="/iisadmpwd/aexp3.asp"This page displays the password change form when SSL is not used.
    AuthNotifyPwdExpURL = "/iisadmpwd/anot.asp"This page appears when a user's password expires earlier than the number of days that are specified in the PasswordExpirePreNotifyDays entry.
    AuthNotifyPwdExpUnsecureURL = "/iisadmpwd/anot3.asp"This page appears if a user's password expires earlier than the number of days that are specified in the PasswordExpirePreNotifyDays entry when SSL is not used.
    PasswordExpirePreNotifyDaysThis metabase entry specifies the number of days that remain before the client's password expires. This metabase entry also indicates when a password pre-notification message is sent.
  8. By default, these metabase entries are located at the W3SVC level in the metabase. You can use the Adsutil.vbs script to configure these metabase entries. The Adsutil.vbs script is located in the Inetpub\Adminscripts directory on your system. To use the Adsutil.vbs script to configure these metabase entries, follow these steps:
    1. At a command prompt, locate the C:\Inetpub\Adminscripts directory.
    2. Type the following command, and then press ENTER:

      cscript.exe adsutil.vbs set w3svc/MetabaseEntry Value

      For example, type the following:

      cscript.exe adsutil.vbs set w3svc/PasswordExpirePreNotifyDays 4
