XP Blocking all incoming connections - Cannot detect where the problem is

Question

I have the following problem. I have installed KERIO Winroute in a machine. After trying it I uninstalled from the PC. The problem now is that I can´t access that machine from network. It seems like something is blocking all the ports. (I have disabled Antivirus and Windows firewall). Does anyone know a tool to diagnosticate the problem or anyone knows how to solve it?

Thanks,

Ezequiel

Answer 1

You might try checking Security Policy (Start -> Run -> secpol.msc). Sometimes security software will try to enforce local security policies to tighten things up. We have some software that uses IPSec and consistently sets a security policy that mucks up traffic to/from the machine. Look in there for anything out of the ordinary or specifically labeled Kerio or Winroute.

I have no experience with this software specifically, just throwing some ideas out there.

Answer 2

I reinstalled the TCP stack (using the microsoft tool netsh) and that worked for me.
