  • Microsoft Windows XP Media Center Edition Service Pack 2 (SP2)

SYMPTOMS

If you turn on Windows Firewall and then select Allow this computer to use a network scanner in the Scanner and Camera window in Control Panel, you cannot use the Scanner and Camera Wizard to access a network scanner.

  1. Click Start, click Run, type firewall.cpl, and then click OK.
  2. In the Windows Firewall dialog box, click the Exceptions tab, and then click Add Port.
  3. In the Add a Port dialog box, type Scanner and Camera Wizard in the Name: text box.
  4. In the Port number: text box, type 21.
  5. Click TCP, and then click OK.
