I don't recommend having templates in a network location. You have found one
of the reasons. Much better would be to set up a login script that copies
updated versions of the template into the user templates folder of
individual machines. There are a number of reasons for this.

- If the network or server goes down, quite enough of your operations are
likely to grind to a halt without you unnecessarily adding to the list.

- Storing templates & add-ins locally means that users with laptops don't
need a different setup - they just get their updates next time they connect
to the network.

- Templates & add-ins stored locally usually load faster, improving startup
time & response time.

- Templates & add-ins stored locally don't load the network with avoidable
traffic,
improving performance for other network-related applications.

- Editing and updating a template at a network location is much easier if
you don't have to break everyone's lock on the file.
