Bill,
That's the same thing we are talking about.
The problem is those environment variables are
highly variable so you can't talk about a machine's environment.
Two users on the same machine (at the same time) may have

I'm a Unix hacker, so forgive me if my understanding of Windows is a bit
naive. I think, though, that Windows has a set of environment variables
which are system-wide, added automatically to the user set of variables
when a new process is launched. Yes, they can be changed or deleted but
there is a standard set applied to all users.
If that's a correct assumption on my part, there must be somewhere that
can be read from, probably (I would guess) in the registry. So a script
which could read/write those registry keys may do what is required here.
The issue of exposing that to remote machines remains a dangling issue,
though.
Of course, it's not entirely clear we're solving a Python question,
although this discussion may well go more solidly into that space.
add or remove variables too. So when I run python2 I may have
the PYTHONPATH seet to one thing, but if I run python3 I
have it set to something different. And I could be running
both at the same time. And another user (or service) logged
into the same machine might be running a Django web server with
yet another setting. So what is PYTHONPATH for that "machine"?
The USER and HOME Values are set by the OS to different
values depending on who is logged in, but the user can
then change these later, etc...
Even with no users logged in you might have different services
running each with their own environment set up.
It is very difficult for an admin to do anything reliably
based on environment variable settings.

I apologize for not have been clear previously. What I am trying to
access are the Windows system environment variables. The same ones
that are listed out if you type the set command at a command prompt
in Windows.

I have times when it is useful for me to check the

this is quite easy to do while I am using a windows system

I think we are meaning different things by "environment"?
Can you give a specific example?
However, I am trying to do this via a linux workstation
(which is joined to the domain, etc.). I cannot find a native
facility to duplicate the computer management functions, so
I thought I
would write a program to fill the need.
Anything you can do locally you can do on the remote
machine with a combination of ssh, rsh, rlogin, telnet etc.
ssh is the safest but requires a bit more admin to set it
up properly for maximum convenience.
Having got remote access its just a case of figuring out
which of the 500 or so Unix commands you need to
use to do the job... :-)
