If a Firewall on your computer is active, it may be rejecting the necessary network connection needed for the network operations such as network printing, network scanning or network PC-Faxing. In this case, Brother recommends you either disable the Firewall on your computer whenever you use a network feature, or leave the Firewall enabled and adjust the settings.
Step 1: Disable the Firewall settings
For personal Firewall Software users:
(For example, Blackice™, Norton Internet Security™, Tiny Personal Firewall, Zone Alarm®, Sygate and McAfee®.)
For instructions on how to disable this type of program, please refer to the user's guide for your software or contact the software manufacturer.
For Windows® 7 Firewall users:
NOTE: If the User Account Control screen appears, type an administrator username and password and click Yes.
First check your network location.
- Click the Start button => Control Panel => System and Security => Windows Firewall => Network and Sharing Center.

Then disable the Firewall settings.
