Symptoms
Clients cannot access your network shares with Symantec Endpoint Protection installed


Enabling network file and printer sharing

    You can enable the client to either share its files or to browse for shared files and printers on your local network. To prevent network-based attacks, you can disable network file and printer sharing.

    You can enable network file and print sharing in the following ways:

      • Automatically enable the network file and printer sharing settings on the Microsoft Windows Networking tab.

        If a firewall rule blocks this traffic, the firewall rule takes priority over the settings.

      • Manually enable network file and printer sharing by adding firewall rules.

        You can add the firewall rules if you want more flexibility than what the settings provide. For example, when you create a rule, you can specify a particular host rather than all hosts. The firewall rules allow access to the ports to browse and share files and printers. You can create one set of firewall rules so that the client can share its files. You create a second set of firewall rules so that the client can browse for other files and printers.

        Your administrator may not have enabled this option on the client. Users on the client can enable these settings automatically.
