OpenSolaris depend on NIS service when need to determine to resolve the domain name

this linke explain the subject
http://en.wikipedia.org/wiki/Network...mation_Service
and this is the command that resolve my problem

Code:

cp /etc/nsswitch.dns /etc/nsswitch.conf
svcadm enable svc:/network/dns/client:default                
svcadm restart system/name-service-cache:default

Sorry but DNS lookups does not depend on NIS, you can use NIS for name resolution within your own network but that won't help resolve names on the Net.

If you can ping something using its IP address the then the network is okay as you showed:
ping 4.2.2.2
4.2.2.2 is alive

The problem is due to failed DNS lookups as was shown:
# ping www.yahoo.com
Ping: unknown host Yahoo!

As has already been stated you need to mention dns in the hosts line in /etc/nsswitch.conf and you need to populate the /etc/resolv.conf with at the very least a line specifying a DNS server's IP address, e.g.:
nameserver 4.2.2.1

If you do not know what DNS server you should be using, then use the ones provided by OpenDNS | Providing A Safer And Faster Internet so the lines in /etc/resolv.conf would be:
nameserver 208.67.222.222
nameserver 208.67.220.220

Confirm you can ping them and you should be up and running if not confirm that no firewall is blocking things by running:

$ telnet 208.67.222.222 53

If you see the response as below:
Trying 208.67.222.222...
Connected to 208.67.222.222.
Escape character is '^]'.

Then you have connected to the DNS server at 208.67.222.222 on port 53, if it just hangs and you do not see the "Escape caharacter is '^'" then you have not managed to connect to the DNS server and a firewall may be blocking port 53.
