IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs. For information on how to do this, view the "Restoring the Registry" online Help topic in Regedit.exe or the "Restoring a Registry Key" online Help topic in Regedt32.exe.

SYMPTOMS
If you migrate a user to Windows NT from Windows for Workgroups version 3.11 with At Work PC Fax installed, when you try to run Windows NT Mail, the following error message may occur:

Faxstub.dll is not a valid Windows NT image.

CAUSE
When Windows NT migrates the Windows for Workgroups 3.11 settings and At Work Fax is installed, references to a 16-bit DLL for the Fax option are placed in the registry. Because Windows NT Mail is 32-bit, 16-bit DLLs will not operate.

NOTE: The settings are migrated from the Msmail.ini file. To prevent additional new users from having these setting migrated, remark out the fax settings in the Msmail.ini file.

RESOLUTION
To eliminate this error message, remove the references to Faxstub.dll and the Fax menu from the Registry with the Registry Editor (Regedt32.exe), using the following steps:

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys And Values" online Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" online Help topics in Regedt32.exe. Note that you should back up the registry before you edit it.

  Go to the following key: "HKEY_CURRENT_USER\Software\Microsoft\Mail" Delete the Providers key. Delete the EFAX Transport key. In the Custom Commands Key, delete all Values that reference Fax commands. Delete the Value Fax= from the Custom Menus Key. Delete the CustomOptionsHandler Value in the Microsoft Mail Key. Delete the Value referencing Fax.Encrypted from the Custom Messages Key.

Windows NT Mail should now run without the above error message. The At Work PC Fax feature included with Windows for Workgroups version 3.11 does not work under Windows NT.
