You can use this site for external nmap:

Also, if you have an older or spare PC you can use:

Clarkconnect, IPCop, or Smoothwall as a gateway router. I use Clarkconnect and it works great.

Also checkout Systernals' Process Explorer as an alternative to Task Manager. It will help show you what's running a lot better. I see that HTRegz has already pointed out tasklist /svc, which is very helpful.
