Thanks, I've almost cracked it now! 2 out of 3 phones are OK, but the third
phone sticks on the Universal Application Loader. I've put a packet sniffer
on the network, and I can see it requesting a DHCP address which isn't on my
network (some legacy config presumably?), and when that times out, it
requests and is issued with an address that is valid for my network, but
then never attempts to connect to any TFTP server. I then set up a dummy
network (DHCP, TFTP server) which matches the network parameters of the
legacy config, and I still don't see any TFTP requests. Any suggestions on
what to do next? I'm out of ideas...
