I finally think I've sorted it out.....
I uninstalled and reinstalled the vnc enterprise on my problem machine
(pc2). Then i checked on both machines (pc1,pc2) using
http://www.gotomyvnc.com/ with this result.
I will check tomorrow if I can connect on both pc's from work
Checking you out at IP address "81.191.xxx.yyy"...
81.191.xxx.yyy is accepting connections on Display 0 (TCP port 5900).
81.191.xxx.yyy is accepting connections on Display 1 (TCP port 5901).
81.191.xxx.yyy is not responding on Display 2.
81.191.xxx.yyy is not responding on Display 3.
81.191.xxx.yyy is not responding on Display 4.
81.191.xxx.yyy is not responding on Display 5.
81.191.xxx.yyy is not responding on Display 6.
81.191.xxx.yyy is not responding on Display 7.
81.191.xxx.yyy is not responding on Display 8.
81.191.xxx.yyy is not responding on Display 9.
