Hi friends
recently i have installed SXDE 1/08 into my machine,and i installed wifi driver also
its working fine,Recently i was unable to connect to Internet,I have not changed any configurations and any installations,thing is that i got my iwk0 interface is UP and IP address also and i can able to ping my gateway and other machines in the same network btw No proxy server but my institute have firewall
but why it is behaving like this...any help

#ifconfig iwk0
iwk0: flags=201004843<UP,BROADCAST,RUNNING,MULTICAST,DHCP,IPv4,CoS> mtu 1500 index 2
	inet 192.168.11.14 netmask ffffff00 broadcast 192.168.11.255

# cat /etc/hosts
127.0.0.1 loghost solaris

#svcs physical
disabled       14:24:57 svc:/network/physical:default
online         14:24:58 svc:/network/physical:nwam

bash-3.2$ cat /etc/resolv.conf
nameserver 192.168.1.234
nameserver 202.88.238.3
nameserver 202.88.238.5
bash-3.2$ nslookup www.google.com
server:      192.168.1.234
address:     192.168.1.234#53

Non-authoritative answer:
www.google.com canonical name = www.l.google.com.
Name: www.l.google.com
address: 209.85.153.104

It looks like the first DNS server is part of the corporate network and could even be on the same subnet if the netmask has been set too tight.

Does running a:

# netstat -rn

report the expected default router?

Can traceroute and/or ping reach Google

well..Thanks Tony
I am not good at Netwotking
here is the output of netstar -rn and traceroute

bash-3.2$ netstat -rn

If nslookup resolves www.google.com but not traceroute, you might have a hosts entry missing the dns service in the /etc/nsswitch.conf file.

thanks for your replies..I re-installed sxde 1/08 into my machine..its working fine now

Quite overkill and quite an old release too.

I would suggest you to install a recent Solaris Express or OpenSolaris release instead.
