    Solution

      1. Insert the "LBP5000 User Software" CD-ROM supplied with the printer into the CD-ROM drive.
      If CD-ROM Setup appears, click [Exit].

      2. From the [Start] menu, select [My Computer], right-click the CD-ROM icon, and then select [Open] from the pop-up menu.

      3. Double-click [English] -> [WF_UTIL] -> [CNAC4FW.EXE].
      IMPORTANT
      You can also run the utility by selecting [Run] from the [Start] menu, entering "D:\English\WF_UTIL\CNAC4FW.EXE", and then clicking [OK]. (The CD-ROM drive name is indicated as "D:" in this troubleshooting. The CD-ROM drive name may differ depending on the computer you are using.)

      4. Click [Unblock].
      NOTE
      You cannot click [Unblock] if the firewall is already configured to unblock communication with client computers.

      5. Click [OK].
      NOTE
      To check if the Windows Firewall block has been properly cleared, select [Control Panel] from the [Start] menu, then click [Network and Internet Connections] -> [Windows Firewall].
      Make sure that the [Canon LBP5000 RPC Server Process] check box is selected in the [Exceptions] sheet in the [Windows Firewall] dialog box.
