No, the Windows clients use separate code.  Take a look at
src/WINNT/afsd/cm_vnodeops.c, function cm_Lock().  It looks for lock
conflicts in a chain of lock structures stored off the scache entry.
It appears that the Windows client is ignoring the byte range and locking
the whole file in all cases.
