Thanks CajunCenturion for your input, saves me the time of changing the code. I am however having problems getting it to work as I would like. I have setup a timer to check every second to see if I am connected (I will change the period when I am finished testing). The code always detects that I am connected correctly, however it is not so clever detecting that I have disconnected. On a Lan for example if I pull out the network cable it does not detect that I am no longer connected. I have to go into Network settings and disable the LAN(Win2000). I also have the same problem when connecting Via a modem. When I disconnect it still assumes that I am connected. I have pasted the code that I have used below. Any assistence would be appreciated.
