If you have a firewall the proper ports need to be forwarded to the machine running the DNAS. If you are running Internet Connection Sharing the SHOUTcast ports need to be set to 1023 or below. Try changing YPort in the DNAC config to 666.

-1 thing that happened to me, same error except i was using that port for WIN MX, im guessing you could use the same port for KAZZA or some other p2p program, anyway i turned off winmx and it worked so basicly im saying, You cant have 2 programs using the same port[i.e. winmx set to port 8000 and winamp set to 8000 , will cause errors]
