Use PHP to first copy() the file from the server to a temp directory
on my
web server and then open the document from the temp dir?
PHP cannot access the file because the user it's running as has no
network access. It has nothing to do with the method you use to access
the file in PHP so copy will not work either.
If that other server is publicly accessible your best bet is to serve
the file directly on that server - i.e. do an HTTP redirect to that
file on the other server. If not then you're left with enabling
network access for the PHP user. A quick Google got me this: http://support.microsoft.com/kb/207671
but there are other references out there.

Stut,
If I copy the link from the error message and paste it into a
browser running from my PHP server, the file comes up just fine.
Should I try mkdir() or mkpath() to set the server and folder
location and then try it from there?
The user PHP runs as needs to be able to access it, not you. I'm
guessing you're on Windows...
If you're using IIS then it's the IUSR_machine user which doesn't
have
access to the network by default. You can enable it but I can't
recall
how off the top of my head and you may want to reconsider because
it
leaves the server a lot more open should IIS/PHP/else be
compromised.
If you're using Apache on Windows then you'll need to check the
service configuration to see what user it's running as.
It can be done somewhat securely by mapping a network drive and
then
granting permissions to it specifically, rather than the network
itself.
(I believe...)
It's been a while since I've used Windows but IIRC you need to
enable
network access for that user at the lowest layer (i.e. system
policy)
and then normal access rules apply, but I could be wrong. Either way
I'd avoid doing it if at all possible.
I think after XP SP2 it got a bit more granular. However, I'm no
MCSE,
so don't take my word for it. :) I do agree with you, anyway, that
the
user a webserver is posing as should not have access to network
resources like this.
I digress.
