You might need to write your own dhcp management thread which calls
the dhcp state machine as needed, or calls the init_net() function
with your static addressing information.

By NTP you mean SNTP? You should be able to call
cyg_sntp_set_servers() at anytime to tell it about a change of unicast
With DNS similarly cyg_dns_res_start() can be called at any time to
indicate a new server.
