I don't guess there's anything we can do to get Word to put its temp files
on C: even when working with a networked document?
Not directly. The temp file locations are hard-wired.
One approach is to manually copy the DOC file from the server to the
local PC and open it in Word there. Copy it back when you are done. At
th every least you should try this once to see whether it makes a
difference.
Another thing to consider is the "make local copy" option. Here are
some notes about that possibility:
*******
Word 2002 has an option called "Make local copy of files stored on
network or removable drives". The option is located in Tools | Options
| Save, and is off by default. (You can also tamper with the registry
to override this setting, see the article.) The explanation of what
the option does is found in article 277010 and is rather complex. Here
is how I understand it.
First, this started as an attempt to eliminate the problems with using
files on floppy disks. (It seems appropriate that Microsoft should
finally have a shot at fixing this problem now that floppy disks are
in the twilight of their career.) When you use Word 2002 to open a
file on a removable medium of 3MB or smaller total drive size (i.e. a
floppy disk), Word first makes a copy of the file in the TEMP folder,
then opens the copy. All of Word's temporary files are thus on the
hard drive, so Word does not run out of space. Whenever you push Save,
Word updates both the temporary file and the original on the floppy.
When you close the file, Word deletes the temporary copy file. All of
this is built-in and not optional.
What setting the option does is to enable all of this mechanism if the
file is on a network or removable drive that is larger than 3MB.
(Actually, the article disagrees with itself on whether the copy is
actually made for large drives. Testing is needed.)
However, Microsoft has also grafted on another piece of function,
which is controlled by this same option. It seems that in prior
versions of Word, if your computer went into Suspend mode to reduce
power, all file locks on the files that you were working on were
dropped. The consequence was that if the file was on a shared network
drive and someone else tried to open it, they would succeed. They
could make changes to the file and save them. Then when your computer
woke up again, you could save changes that you had made to the file,
overwriting the changes the other user had made.
Apparently if you set this new option, Word does not drop the file
locks if your computer goes into Suspend mode, avoiding the
possibility of lost edits by another user. The cost is that since the
locks are held by your suspended computer, the setting prevents any
edits by another user until you and your computer wake up.
The article also claims that if the option is turned on, the usual
"owner file" is not created by Word when a file is opened.

By the way, you said that the document is 800 pages, but I didn't
notice where you said how big it is in MB. I have a simple (no
pictures, etc) 500 page document that takes about 5MB and is quite
quick to deal with.
