This isn't strictly true.  The auto-registration of the name by
afsd_service.exe will enable the "AFS" machine name to be discovered
via the NBT Host Names table.  However, DNS lookup comes first and
you would first need to wait for the DNS lookup to fail for each and
every query.  This results in a performance penalty.  If the lookup
doesn't fail, then you end up not being able to find the AFS service.
In either case, we work around the performance issues or the denial of
service attack by placing an entry in the HOSTS file.
