Rsync transfers a regular file by writing its data to a temporary file
in the destination and then renaming the temporary file over the
original.  This is why rsync is attempting renames; I don't know why
they are failing on your particular filesystem.  Possibly another client
of the destination NSS volume had AUTOCHK.EXE open and the NSS
filesystem wouldn't allow the file to be replaced while it was open?

This is probably related to daylight savings time.  Rsync copies mtimes
in seconds-since-the-Epoch, but if the two machines convert these times
into human-readable times according to different conventions, there may
appear to be differences.  See if there are any NSS configuration
settings for daylight savings time.
