Greetings. http://i448.photobucket.com/albums/qq207/hekyumi/ESET/1.jpg WinXP hosted as a print server, having few LAN PC connect to it for printing. Notice that there are too much traffic at the printer and file sharing ports. Port 135~139 can be block to minimize the traffic, but if I block the port 445, the printer sharing won't work. Already scanned the PC using ESET, SuperAntispyware, Kaspersky, Panda, Spy Bot SnD, etc.. with no virus found. Please help!!!!
