What is computer info Tech? I can use some help on a network issue... I have an unwelcome arp entry that I can not clear. On the good side I have all the pass codes, and user names off the machine that hacked me. The poor fella lost all his Virgin Atlantic miles last night. I'm about to delete all his email accounts. (Someone has placed a man in the middle attack on me) If I cant clear the arp entry I will clear his computer.
