DNS resolver Troubleshooting

[Andre Machado_1]

Hi,

I have some machines resolving names in a two Windows 2000 DNS Servers ( Primary and Secundary ).

I did configured in a resolv.conf the name servers of my DNS servers :

search std.com.br
nameserver 192.128.2.88 # Primary DNS Server
nameserver 192.128.2.89 # Secondary DNS Server
domain std.com.br

When my Primary DNS server fails the resolver receives time-out to receive the answer.

If I change the resolv.conf file to:
search std.com.br
nameserver 192.128.2.89 # Secondary DNS Server
nameserver 192.128.2.88 # Primary DNS Server
domain std.com.br

my resolver havent a problem.

I??d like do know if have some configuration of time-out of the resolver, or some configuration on nsswitch.conf to change the DNS server when the DNS server are unavaiable.

Thank yout for your help.

Best regards

Andre Machado

Say if you want to use DNS as the very first element in the fallback order, follow by NIS and the the host files, you would have this in /etc/nsswitch.conf file.

DNS [notfound=continue] NIS [notfound=continued] files
