Permitting clients to browse for files and printers in the
network
You can enable the client to either share its files or to browse for shared files and
printers on the local network. To prevent network-based attacks, you may not
want to enable network file and printer sharing.
You enable network file and print sharing by adding firewall rules. The firewall
rules allow access to the ports to browse and share files and printers. You create
one firewall rule so that the client can share its files. You create a second firewall
rule so that the client can browse for other files and printers.
The settings work differently based on the type of control that you specify for
your client, as follows:
Client control or mixed
control
Mixed control
Server control

on page 221.
Users on the client can enable these settings automatically by
configuring them in Network Threat Protection.
A server firewall rule that specifies this type of traffic can
override these settings.
These settings are not available on the client.
