Hi Broonie
Although this behaviour can be frustrating, I believe it is "by design".
Mapped drives are specific to the User context. For example, If you map
a drive as "User 1", then log in again as "User 2", you won't see the
same mapped drives that User 1 defined, you need to map them again as
User 2.
In the "Run as Admin" case, you understandably *think* you are running
as the same user, just with elevated privileges. But those elevated
privileges come in the form of a new and different user token. So, the
MPR and WNet modules consider that you are a different user when you run
"as administrator" - because you have a different user token - and give
you a new, unique set of drive mappings: initially empty, if you haven't
defined any mapped drives "as administrator".
The easy part of the solution is to map the drives you need, while in
the context of running "as administrator". The tricky part is that
Windows Explorer can only run a single instance in a session; so you
cannot use the Explorer "Tools, Map Network Drive" option to map the
drives - Explorer will still be seeing your user context as a
un-elevated user. The slightly clunky workaround is to open a Command
Prompt "as administrator" and map the drives at the command line, using
a "NET USE" command. The drives mapped this way should be visible to
other processes which you are running "as administrator", even if they
don't show up in Explorer.
This behaviour is unintuitive, non-obvious and kind of annoying. But,
that's how it works :-)
Hope this helps a bit,
Andrew
