Dead DNS

[Mark]

My Solaris 9 box will not resolve any addresses.
It is DHCP and the resolv.conf has not changed.
I've tried releasing the IP and rebooted.. no help.
This all started when i tried to install a second NIC (This is still
not working , But thats another story)

I can go to sites using the ip or putting the ip in the hosts file but
this wouls not fall into the category of efficient surfing ;-)


Thanks
Mark

It was the nsswitch file,
any ideas would cause this to happen ?

The /etc/nsswitch.conf file installed by the system from SUNWcsr has this
line:

hosts: nis [NOTFOUND=return] files

To use DNS you require:

hosts: files dns

Did you run sys-unconfig at any point? This will overwrite
nsswitch.conf.
