Outlook 2003 - Change Password failures

[Doug]

Greetings,
I have a set of users that will be accessing our Windows 2003/Exchange 2003
server using Outlook 2003 over RPC on HTTPS. I need to enable them to change
their password through the tools>options>other>advanced>custom
forms>ChangePassword button.

These users/machines will not be part of the domain and the only access they
will have is RPC over HTTPS.

I have diagnosed that Outlook 2003 will only allow you to change your
password this way if you are on a computer that is a member of the same
domain as the Exchange server. But if the computer is not a member (using
normal RPC communications or RPC Proxy) the password change fails. The error
message is "The NT domain password could not be changed. A required action
was not successful due to an unspecified error."

I attempted to implement the registry change
HKEY_LOCAL_MACHINE\system\currentcontrolset\control\lsa TCPIPClientSupport

But it does not seem to work.

Thanks,
Doug

You will not be able to change your password through OL2003 when connected
through RPC over HTTP and you do not have TCP-RPC connectivity to the Domain
controller. As most implementations will be for internet access, this won't
work in most implementations.

Outlook 2003 simply issue a platform call to change your password, as this
is a platforms call, it will not be tunneled through HTTP, but attempted
with RPC over TCP to your logon domain controller which will fail if you are
on the internet.

Change password functionality is available for remote users with OWA.
