Hello,I was configuring a new firewall in the company when I accidently noticed in the log file that a certain IP is broadcasting packets to udp port 137 and sometimes 138, when I disconnected that PC I noticed other PCs started to broadcast the same packets ! I dont know what causes them, I disconnected another one and ran a full scan using "Super Anti-Spyware" with latest definitions and no results were found.The port maps to NetBIOS Name Service, but we dont have such service running in our network! we do have a DNS server though.Is this a normal behaviour or not ?Thanks..
