What happened if you tried to access a network file bigger than 2GB from MS-DOS?

One of my friends is into retrocomputing, and he wondered what
happened on MS-DOS if you asked it to access a file on a network
share that was bigger than what FAT16 could express. My friend was
under the mistaken impression that when MS-DOS accessed a network
resource, it was the sector access that was remoted. Under this
model, MS-DOS would still open the boot sector, look for the FAT,
parse it, then calculate where the directories were, read them
directly from the network hard drive, and write raw data directly
to the network hard drive. This is not how it works. Raymond Chen
is an international treasure.
