You cannot "solve" this. It's just the way windows works: it caches netbios 
names and doesn't ask on the network every time. The reason for this is that it 
tries to prevent broadcast flooding of the LAN, since netbios names are 
resolved using local UDP broadcast (unless a central server is used, which 
isn't the case for lwIP).

I'm afraid I don't understand that. If you mean letting the DHCP client pass a 
hostname (selected by lwIP) to the DHCP server and then being able to ping that 
hostname: this cannot be easily configured, as you need a linux/unix DHCP 
server that is bundled with a local DNS server and the client PC trying to ping 
via hostname has to use that DNS server. It can be done, but I don't think this 
turned on by default.
