DNS resolution problem

[Guillaume]

Hi,
On fedora core 6, i have some problem of dns name resolution with some programs.
If i use wget or firefox (and maybe other progs) i can't use dns name
to access websites, ie :
--01:24:49--  http://www.symantec.com/
Résolution de www.symantec.com... 1.0.0.0
Connexion vers www.symantec.com|1.0.0.0|:80...échec: Le réseau n'est
pas accessible..

On every test, dns return me 1.0.0.0 IP address for every servers...

If i use the ping command address is ok.:
]# ping www.iana.org
PING www.iana.org (192.0.34.162) 56(84) bytes of data.
64 bytes from www.iana.org (192.0.34.162): icmp_seq=1 ttl=43 time=211 ms


I found somewhere on google i have to restart the nscd daemon, but it
does not solve my problem.

Does someone can help me ? :)

Thanks,
