SYMPTOMS
If you install Services For Macintosh (SFM) version 3.1, then change the drive letter of the drive that NT is installed on, the MacFile control panel applet no longer appears in File Manager. This can also happen if you upgrade by installing Windows NT version 3.5 over Windows NT version 3.1 and the drive letters had been changed the same way.



CAUSE
In Windows NT 3.1 the path to the .CPL file for the MacFile menu item was hard coded to the system root directory:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\ FileManager\AddOns\AfpManager: REG_SZ: E:\NTS612\System32\sfmmgr.cpl

(in this example E:\NTS612 is where Windows NT 3.1 was installed)

Changing the drive letter renders this path invalid.



RESOLUTION
In Windows NT version 3.5 the path is not hard coded in the registry. Edit it to read as shown below using REGEDT32.EXE:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ FileManager\AddOns\Afp Manager: REG_SZ: sfmmgr.cpl

WARNING: Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to reinstall Windows NT to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk.



STATUS
Microsoft has confirmed this to be a problem in Windows NT version 3.1. This problem has been corrected in Windows NT version 3.5.
