Stop process

[King Kong <kingkong21 () arcor de>]

Hi all,

I am a newbie so maybe this is a stupid question.
I am writing my own honeypot for Windows. So far so good but when I try to 
send back my data packets an answer from my Windows has already been made. 
The packets (Blaster) arrive on port 135 on my machine. What process do I 
have to stop and how to stop them so that my OS does not automatically send 
any reply. I am using Windows (XP,2000,98)

Thanks in advance
