I have made some simple tests and get the conclusion that SHARE is looked
for in the place from which COMMAND.COM is loaded. If your SHELL variable
points to a non-root directory COMMAND.COM, SHARE won't be loaded if
it isn't in that directory, even if it is in the root. If you have no
SHELL variable, it will be loaded if it is in the root.

BTW: I there a method of disabling SHARE locks without rebooting?
