SYMPTOMS
When you add a new key to map Windows 16-bit .INI files to user specific entries in the Microsoft Windows NT Registry using the Software\Microsoft\Windows NT\CurrentVersion\IniFileMapping key, then mappings have no effect. Mappings created with previous versions of Windows NT do not work either.



CAUSE
IniFileMapping does not work if the application calls the Windows Kernel API function GetPrivateProfileString with a fully qualified pathname (for example, C:\PROGHRAMS\MYAPP\MYAPP.INI).

This functionality changed in Windows NT 3.51 because applications failed if they tried to call GetPrivateProfileString with a fully qualified pathname because they got their information from the Windows 3.1 WIN.INI entries. The fix mentioned below treats references to WIN.INI as a special case. If WIN.INI is referenced, the standard WIN.INI file is be used.



RESOLUTION
To correct this problem, install the latest U.S. Service Pack for Windows NT version 3.51.



STATUS
Microsoft has confirmed this to be a problem in Windows NT version 3.51. This problem has been corrected in the latest U.S. Service Pack for Windows NT version 3.51. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
