Hi Russ
Yes, it is possible for users to share a template .dot file on a network.
This is possible because of the two ways that a template interacts with a
Word document. When a Word document is created, it inherits certain things
from its parent template. When a Word document is open, the template to
which it is attached makes certain things available to the document (note:
"makes available to", not "stores in"). See the following for more info:
What is the relationship between a Word document and its template?

In the normal course of events, if you have a template on the local
machine, you might have open several documents that are attached to that
one template. Similarly, several users can each have open several
documents that are all attached to one template on a server.
If you want to prevent users from making changes to a template stored on a
server, then you should mark it as read only.
However, there are several disadvantages to setting up an organization so
that users share a template:
(a) if the network goes down, no-one can do any work
(b) if a user unplugs the laptop and takes it home, or to the local coffee
shop, or to a meeting room, or on to a plane, then they can't do any work
(c) if the name of the network share changes, Word will take ages to open
the document (see

(d) updating the template can be difficult.
