  2. On the navigation bar, click Network, and then click Connectivity.

  3. Right-click Server firewall, and then click View firewall properties.

  4. Click the Advanced tab, and then click Manage rules.

  5. Click Allow a program through Windows Firewall.

  6. On the Exceptions tab, scroll in the Program or port text box until you find the port name that you want to close.

  7. If you want to temporarily disable the port, clear the check box, and then click OK.

  8. If you do not plan to use the program that requires that port, click Delete to permanently delete the program name and port number, click Yes, and then click OK.
