After you install Microsoft Windows XP Service Pack 2 (SP2), the Computer Browser service does not start when you restart your computer. The following event is logged in the system event log:
This problem occurs because Windows XP SP2 installs Windows Firewall. Windows Firewall may block the ports that are used for file and printer sharing. If these ports are blocked, the Computer Browser service cannot start.
To resolve this problem so that the Computer Browser service starts, follow these steps:
Whether the File and Printer Sharing check box is selected may affect the behavior that you experience. By default, the File and Printer Sharing check box is selected if you upgrade from an earlier version of the Windows operating system that has existing shared resources, or if you upgrade your Windows XP Service Pack 1-based computer that has existing shared resources. Therefore, you will not experience the behavior that is mentioned in this article. However, if no shared resources exist before you install Windows XP SP2 or if you integrate Windows XP SP2 with the Windows XP installation, the File and Printer Sharing check box is not selected, and the Computer Browser service does not start.
