Add or Remove Programs entry for Windows XP Düzeltme - KB886185. This security update for Windows XP addresses a problem with the Windows Firewall when using a dial up connection that causes your computer to be vulnerable to all outside conputers.

This update helps narrow the definition of the My network (subnet) only, or local subnet, scope option in Windows Firewall. This is helpful in situations where Windows Firewall would consider a large network to be on the local subnet because of how the dial-up software configured the route tables.
