I recently installed an LS-120 floppy drive on my NT 4.0 machine. Now an error message appears after login which reads POPROXY.EXE - Ordinal not found. Ordinal 6662 could not be located in DLL MFC42.DLL. I first tried deleting the error by reloading SP4 with no luck. I downloaded an updated version of MFC42.DLL but cannot replace the original file since file is in use. Can anyone tell me what process uses this DLL so I can disable the process and update the DLL? Any other tip that will allow me to remove the error will be appreciated as well.
