SMB, or Server Message Block, is a logical construct in computer networking that allows network-enabled devices such as your computer and PS3 to connect and share files on a LAN, or local area network. Mounting a SMB on your PS3 has a variety of benefits such as allowing you to enjoy media from other devices on the TV connected to you PS3. In order to create the connection between your computer and PS3, you must enable several settings within Windows Media Player and Networking.
Click the "Start" button and then click "Control Panel."
Click on "Network and Sharing" and then click "Change Advanced Sharing Options." Click on the button next to "Turn on network discovery" and the button next to "Turn on file and printer sharing." Click "OK." The "Media Sharing" window appears, which is used to control sharing options for the default media player on Windows, Windows Media Player.
Click the drop down box next to "Show devices on" and select "All networks." Next to the device that represents your PS3, click the drop down menu and select "Allowed" and then click "OK."
Power on your PS3 and then select either the "Photo," "Music," or "Video" icons from the system menu.
Click on the "Windows" icon from the list of available media. Files or media that the PS3 can play is shown in the resulting list. Select the folder to display its contents if your media is organized in folders.
Write down the MAC address of your PS3 to easily identify it in Windows Media Player sharing lists, if necessary. Ensure that both the computer and PS3 are on the same network.
