MrxSmb Problem

My system keeps getting warnings from MrxSmb with event 8006. “The browser has received an illegal datagram from the remote computer BICE-HOME to name BICEHOME on transport NetBT_Tcpip_{E265FCDB-. The data is the datagram.” This is preventing me from going to several of my websites – bank and ecommerce. How can I fix this? Anyone have any suggestions short of a baseball bat? I have been on with tech support for 4 days and have had no success.
