DNS issue.
We are able to ping the server:
(hqb) [SU] # ping 10.5.3.180
PING 10.5.3.180: 64 byte packets
64 bytes from 10.5.3.180: icmp_seq=0. time=0. ms
64 bytes from 10.5.3.180: icmp_seq=1. time=0. ms

----10.5.3.180 PING Statistics----
7 packets transmitted, 7 packets received, 0% packet loss
round-trip (ms) min/avg/max = 0/0/0
But the nslookup is not able to resolve the the dns server name.
(hqb) [SU] # nslookup hpi.dhq.lr.org
*** Can't find server name for address 10.5.3.180: Non-existent domain
*** Default servers are not available
Using /etc/hosts on: hqb
looking up FILES
Trying DNS
*** can't find hpi.dhq.lr.org: No response from server
The same ip is getting resolved for other Linux and windows servers withing our network, however the same is failing for all the hpux boxes. Kindly provide suggestion/inputs to resolve the same. Thanking you in advance.

Re: DNS issue.
#
# /etc/nsswitch.conf
#
# This file is for use on systems that are not running DNS or NIS.
#
# In this case we request that the resolver looks in local files only.
#
# See the Adminstering Internet Services Manual and the switch(4) man
# page for more information on the name service switch.

Check with your Network administrator to see that UDP port 53 (domain) is not blocked by a firewall rule.
