SYMPTOMS
You may receive the following error message when attempting to view the properties of a recipient in an Exchange Server site that has had the Optus Faxsys Connector removed.

Extension "Faxsys" could not be loaded.

The extension for the Microsoft Exchange Administrator's CPU type has

not been installed in the site.

ID no:c1031667

Abort Retry Ignore



CAUSE
The connector's .dll files are being called by the Exchange Server Administrator program but can no longer be accessed because the connector has been removed. This is a result of an incomplete removal of the connector.



WORKAROUND
If possible, run an Uninstall program for the connector. If no automated uninstall method exists for the connector, proceed as follows.

 After removing the Optus Faxsys Connector, verify that all mention of Faxsys has been removed from the registry and in the Exchange Server Administrator program.

  In the registry check the following key for any left over keys:      Hkey_Local_Machine/System/CurrentControlSet/Services  In the Exchange Server Administrator program, verify that under Site, Configuration, there is no mention of Faxsys in the Add-Ins container or the E-Mail Address Generators container. Also, make sure there is no entry, or the Faxsys proxy is not selected on the Site Addressing properties. (Click Site, click Configuration, and then double-click Site Addressing in the right window to open the Properties page. Select the Site Addressing tab to see the Faxsys proxy option.)  You will also have to start the Exchange Server Administrator in raw mode.

WARNING: Using the raw mode of the Exchange Server Administrator program (admin/r) incorrectly can cause serious problems that may require you to reinstall Microsoft Windows NT Server and/or Microsoft Exchange Server. Microsoft cannot guarantee that problems resulting from the incorrect use of raw mode can be solved. Use raw mode at your own risk.

 At a command prompt, type:

c:\exchsrvr\bin\admin /r

</li> Select the Recipients container, and on the File menu, click Raw Properties.</li> In the Objects Attributes list, select Extension-Name-Inherited, and remove Faxsys.</li></ol> </li></ol>

MORE INFORMATION
