nslookup issues urgent
bwadmin@as1$ nslookup as2.synapse.com
*** Can't find server name for address 192.168.0.16: No response from server
*** Can't find server name for address 192.168.0.17: No response from server
*** Default servers are not available

[Sandeep] /etc/resolv.conf have already 192.168.0.16/17 defined. I can also ping these servers from as1. What could be the issue? One reason could be that DNS service is not running on these DNS servers. Comments?

B. bwadmin@ns1$ nslookup as2.synapse.com
*** Can't find server name for address 127.0.0.1: Unspecified error
*** Default servers are not available

[Sandeep] Typically this error comes if /etc/resolv.conf is not defined. In this /etc/resolv.conf is defined and name servers are pingable. what could be the error? Any help is appreciated as it is quite urgent

is your lan card up? (check with ifconfig... do you have a default route set?...)
The surprise is your loopback giving unspecified error...

What about /etc/nsswitch.conf ?
do you see 'dns' beside 'host'

eg . ..

hosts: files dns
