I have noticed that on all of our new 6.5 servers it seems autoexec.ncf is
being backed up. There is a file called autoexec.bak, autoexec.ncf.bak
and several similar to autoexec.ncf_1129324114437.

Some of them are dated the same and are the same size, but all are
different than autoexec.ncf. Is this normal?
