Excessive Outbound Traffic on UDP Port 137
Posted on 2008-06-23
I've been noticing in my firewall logs an excessive amount of outbound traffic on udp port 137 from a single workstation. This port is blocked in my firewall, so it's not getting through, but I wanted to know if anyone could help me find the source of this traffic.
I have run CA AntiVirus and Anti Spyware as well as Spybot. The AV scan was clean and the spyware/adware scan only came up with a handful of cookies that have been removed. Netstat and Nbtstat both seem clean as well.
Thanks for the help.
