BDC Excessive Broadcast Traffic on Src and Dst Port 137

I have a BDC that was saturating a LAN segment today.  When I sniffed the traffic, the BDC was pumping out Netbios Broadcast traffic with both source and destination port 137.  Is this normal?  The IP configuration of the BDC is correct.

Hi asafayan,

Do you really need to enable Netbios for your network?  Is there wins server around?  You might want to check out if there are virus in this machine, make sure all security patches are installed.  Try to turn off Netbios and check or try turning off Computer Browser just for testing.  List all related event warning here.

YOu may have Blaster or Welchia on the network, may be on the BDC.
