Accessing Shared Drive on Windows

I am running a Lua program on a Windows 10 machine. This Windows 10 computer is networked to another Windows 10 computer and this other computer is sharing its D: drive with my computer. The shared drive is called the O: drive by my computer.

When I open a cmd window on my computer and type:

type "O:\Data\config\file.xml"

I get the contents of file.xml in my cmd window. However, if I run this same command through Lua:

f = io.popen([["type O:\Data\config\file.xml"]])

output = f:read("*l")

Then output returns as nil.

This behavior is true of any command involving the shared O: drive, not just type. Similarly, I have some bat scripts that reference the O: drive, and I call these using os.execute, but they are not able to accomplish their task (I can see they are actually executing, just not correctly). However, if I run similar commands or scripts with the local D: or C: drives, I do not have this issue.

Any ideas as to what could be different between these two calls? Is there a different way I can call the O: drive?
