It had way too many protocols installed, tunnelling hooks in it, it wouldnt get on the net. I removed bunches of those, but it still has windows firewall and mcafee AV/sysprotect running. I'm going to try and run zonealarm on it. Then I'll try putting in a router beteen the cable modem and laptop.

It blocked cvpnd.exe and logged a boep (buffer overflow exploit prevention) event. McAfee AV has a similar feature so that I think its boep blocked your instance of Cisco VPN client.
