This error indicates that the DNS name you are trying to resolve does not exist.

Things to try:

  * Check that the hostname portion of the URL you are using is correct.

  * Check that iPXE is using the correct DNS server.  You can view the DNS server used by iPXE using the command ''show dns'':<code>  iPXE> show dns
  net0.dhcp/dns:ipv4 = 10.0.0.6</code>

  * Check that your DNS server is prepared to handle recursive queries.

  * Check that your DNS server is responding via UDP.  iPXE will not retry via TCP if a response is too big.
