mbesspiata, Stephan and Charles have given you the links and information to do what you ask for. A global template file, either put into another computer's Word Startup folder (if you want the macro code available automatically), or in any available folder if you want to be able to load it (or unload it) dynamically.

Yes you can also use an export\import file, but as Charles mentions, it is doing it the hard way, and not needed. Plus it only works one at a time; if you want multiple other computers to have access over a network, then a global template is the only way to go.
