Is my new Windows network safe?

Expert Jonathan Hassell answers a user's question about the security of a new small at-work network.

We have just set up a workgroup in our small office (4 computers - no server). Is there any way to prevent someone from being able to join the workgroup with their laptop and thus having full access to all the folders on all the computers?
Sorry – anyone who has the name of the workgroup can join the workgroup. It's a free for all. To have control over who can join a Windows network, you'll need to deploy a domain.
