The local SYSTEM account can do things that require access only to resources
on the local system that do not depend on a specific user context.
Generally speaking, processes running under SYSTEM cannot access resources
on remote machines.

Within those bounds, you shouldn't have any problems.

A couple of examples of things that are unlikely to work:

- sending email via Outlook (or MAPI based CDO) automation (reason: user
mail profile required)

- accessing files via UNC paths (reason: any UNC reference is treated as
remote, even if it references a share exposed by the machine that is running
the process)

To determine why a specific script fails to work as expected as a
Win32_ScheduledJob (AT based) job, one would have to examine the source code
of the specific script with the SYSTEM account's security context and
network reach in mind...
