Macintosh Change Password Fails on Down Trusted Domain PDC

• Microsoft Windows NT Server versions 3.51, 4.0
• Microsoft Windows NT Server version 4.0, Terminal Server Edition

SYMPTOMS

In a multiple master domain environment, initiating a change password from a Macintosh client without specifying the domain name may fail. The error report to the Macintosh client is:

Your password could not be changed.
Please try again or see your server administrator.

CAUSE

Change password requests initiated by a Macintosh client are forwarded to a computer running Windows NT Server and running Services for Macintosh. The server then initiates the change password request on behalf of the Macintosh user. When the user account name is received with no specified domain name, requests are sent to a list of trusted domain controllers (DCs) under the multiple master domain model. In this case, an unexpected error was returned from the change password request because a DC in the list of trusted DCs was down. Because of the unexpected error, the complete list of DCs was not processed.

WORKAROUND

The workaround is for users to specify the domain [domain_name\username] in password change requests.

RESOLUTION

The Services for Macintosh file, sfmsvc.exe, was modified to handle the unexpected error code that was encountered.
