But why would the machine have a dial-in IP when it is not dialing in?
As I understood it the machine makes a DHCP call when it connects to the
network - it connects via the LAN and does not dial in to the system. If
it was being taken off-site I could see how this could happen, but not
if its staying in the office plugged into the LAN. Sorry to labour this
but I suspect it shows a lack of understanding of DHCP on my part and
I'd like to understand where I'm going wrong :-)
