Windows Vista File and Printer Sharing Ports
When you enable file and printer sharing in Windows Vista it automatically opens the ports needed to share files or printer in the Windows Vista firewall for you.
What if you’re not using the Windows Vista firewall or you’re using a hardware firewall like a router, firewall appliance, Linux firewall, or a Cisco PIX?
Below is a table that lists all the ports that need to be opened in Windows Vista to share files and printers. You can manually open these ports to enable file and printer sharing on your computer.
