IISADMPWD Change Password application in mixed Exchange 2003/2007 environments


When you are switching over your Exchange 2003 Front-End servers to Exchange 2007 and you use the “Change Password” feature in OWA 2003 you have to keep in mind that you need to install the IISADMPWD application on the CAS servers first.

If you have both Exchange 2007 Client Access servers and Exchange 2003 or Microsoft Exchange 2000 Server back-end servers in your Exchange organization, additional configuration steps are required to enable the Change Password feature to work correctly. To enable the Change Password feature to work correctly, follow these steps:


1. Create the appropriate IISADMPWD folder and virtual directory on each Client Access server. For more information about how to create and configure the IISADMPWD folder and virtual directory, see Implementing the Change Password feature with Outlook Web Access.

2. Follow these steps to create the appropriate registry key on each Exchange 2003 or Exchange 2000 back-end server:

a. Click Start, click Run, type regedit and then click OK.

b. In Registry Editor, locate the following subkey: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeWeb\OWA

c. On the Edit menu, point to New, and then click DWORD Value. In the result pane, name the new value DisablePassword.

d. Right-click the DisablePassword DWORD value, and then click Modify.

e. In the Value data field, enter 0, and then click OK.

3. On each Client Access server, open IIS Manager, and then select Web Service Extensions.

4. In the result pane, select Active Server Pages, and then click Allow.

5. Incorrectly editing the registry can cause serious problems that may require you to reinstall your operating system. Problems resulting from editing the registry incorrectly may not be able to be resolved. Before editing the registry, back up any valuable data.
