Thanks in advance for help on this. I'm currently in the UK & support a machine in the US and have had some problems connecting via ARD, but problem disappears when you DMZ that machine. The problem i now have is another machine has been added to the network and i simply cannot connect to that machine. Everything on it is setup ok, when i try to add the IP to ARD, it accepts it but removes the IP from the other machine. Your help is much appreciated.
