Hi, I'm using a MCB2300 with LPC2368 and the DNS_demo program. But I can't get the DHCP client and DNS Address from TCPNET working. How could i experiment? Thanks!
This is Debug information: DNS Resolver Demo Example

From the log it is obvious that the ethernet is not working, because nothing is received.
Did you check the ethernet cable? For connection with a LAN switch you need a straight-through cable. Some of the LAN switches also have an Auto MDI/MDI-X crossover detection and are able to work with both crossover and straight-through cables.
If there is no problem with the LAN cabling, then there must be a problem with your MCB2300, which needs a repairing.
