Hi Mark
I did as you suggested and commented out "Allow-hotplug eth0 in the /etc/network/interfaces file and it's working fine,
There are still some problems downloading certain services from within the web gui and mounting or creating one particular volume (that happens to have a Windows & Linux partition on it) I may have to wipe these partitions first but I'm not sure how to do that in the NAS terminal, alternatively I suppose I can run any live Linux disc on the NAS and use gparted, but so far I haven't had a lot of time to spend with it so I'll mess around with it tonight and let you know if I have any problems, I also installed puTTY on my pc so I can now log into the NAS via ssh which should make things easier (one keyboard)
Many thanks
Graeme
