nmbd using 50% of CPU time!

Hello All,

I use my macbook pro in a lab that I work in at a university. When I plug in the ethernet cable (connecting my comp to the network), I notice that my cpu usage jumps from near 0% to 50 - 75%. I found that the nmbd program is using nearly 100% of one of the two cores in my CPU!!! I have read that this is part of the samba package designed for windows file sharing. I have turned OFF all sharing on my mac, yet the nmbd problem persists. I am at a loss for what to do now. Please help!
