Shalom,

nsswitch.conf looks good.

nameserver xxx.www.yyy.zzz
nameserver xxx.www.yyy.zzz

This in resolv.conf needs to be a numeric IP address.

It must be a numeric IP address that your server can communicate with on port 53

telnet 192.168.0.10 53

This should go through and get a funny looking prompt with the DNS server.

Is this something just stopped working ? Or never worked ? Is there any other server(s) in the same subnet, with same nsswitch.conf and resolv.conf configuration that works properly ?

Can you ping your nameservers?

Hi,

If yours is private network and do not have public access, nslookup is not going to resolve hp.com

This is because your dns server doesn't have the dns records for hp.com
