Hi there,
You probably need to enable network discovery and file sharing.
Open the desktop Control Panel. If you're in Category view, choose View network status and tasks. If you're in one of the icon views, choose Network and Sharing Center. Then, on the left, click Change advanced sharing settings.
Expand Private or Guest or Public depending on what you've called your current network connection. Make sure Turn on network discovery and Turn on file and printer sharing are enabled, then press Save changes.
