This error indicates that iPXE timed out waiting for a response from the DNS server.

Things to try:

  * Check that the DNS server is online and responding to queries.

  * Check that iPXE is using the correct DNS server.  You can check the DNS server address using the command ''show dns''.  For example: <code>  iPXE> dhcp
  DHCP (net0 52:54:00:12:34:56).... ok
  iPXE> show dns
  net0.dhcp/dns:ipv4 = 10.253.253.1</code>
