How to Configure Change Password for OWA 2003/2007/2010 Mixed Environments

The Change Password feature in OWA will break when you reconfigure the environment to use Exchange 2007 or Exchange 2010 CAS servers as front-end servers for Exchange 2003 mailbox servers.  This is because the the CAS server don't have the necessary ASP pages installed that OWA 2003 links to.

telnetPORT25 wrote a great article explaining the step-by-step process, along with screenshots, to fix this problem.  I'm listing the high-level steps here (mainly to act as my long-term memory).
  • Logon to the Exchange 2007/2010 CAS server
  • Copy the %SystemRoot%\System32\inetsrv\iisadmpwd folder and files from the OWA 2003 FE server to the CAS server's %SystemRoot%\System32\inetsrv folder
  • Open IIS Manager and add a new Virtual Directory off the Default Web Site named IISADMPWD with a physical path of %SystemRoot%\System32\inetsrv\iisadmpwd
  • Right-click the new IISADMPWD virtual directory and select Convert to Application
  • Select the MSExchangeOWAAppPool
  • Restart IIS (iisreset /noforce or select the server in IIS Manager and click Restart)
