Some time ago I ran a web-based security check from Symantec. It identified an exposure with NETBIOS (possibly ports 137, 138, 139?) which it then fixed. I assumed this worked OK as the Network setting in Control Panel is no longer showing NETBIOS entries. After installing PE, the socket list however still shows the NETBIOS ports with 137, 138 showing both TCP and UDP, and 139 TCP only. I don't need these ports (not running a home network) but can't kill or disable them in PE. What can be done to remove them?
