Thanks, I did as you suggested. I had the utility open and I could see my known processes which I closed one by one. Then I started on the (my) unknown ones, none of the ones I closed made any change to the usage. Finally the below mentioned stuff was remaining. I was not able to end any of these processes.

Process   Protocol   Local Address        Remote Address   State
System8   TCP        deve1:microsoft-ds   deve1:0          LISTENING
System8   TCP        deve1:netbios-ssn    deve1:0          LISTENING
System8   TCP        deve1:netbios-ssn    deve1:0          LISTENING
System8   UDP        deve1:microsoft-ds   *:*
System8   UDP        deve1:netbios-ns     *:*
System8   UDP        deve1:netbios-dgm    *:*
System8   UDP        deve1:netbios-ns     *:*
System8   UDP        deve1:netbios-dgm    *:*

deve1 is my machine name.

Please advise.
