Please excuse my error on this file. I quoted information for the NTOSKRNL.DLL and this is NOT the file in question. My bad!
I traced back to try and find the error of my ways: on the RegRun site I referenced, the subject heading is: "Virus Removal Story: ntsystem.exe, ntoskrnl.dll, gviz". I mistakenly scrolled down to the information for the second file.
Howard, you must also be very careful in your spelling: "ntsysten.rnr file you require" is not correct.(Note the 'n' instead of 'm') This is a copy and paste.
