[SOLVED] Name resolution stopped working after upgrade

After I did a system upgrade today, most programs are no longer able to resolve hostnames.

When running ping, for example:

$ ping archlinux.org
ping: archlinux.org: System error

$ nslookup archlinux.org
Server:         172.16.42.1
Address:        172.16.42.1#53

Non-authoritative answer:
Name:   archlinux.org
Address: 66.211.214.131

$ ping 66.211.214.131
PING 66.211.214.131 (66.211.214.131) 56(84) bytes of data.
64 bytes from 66.211.214.131: icmp_seq=1 ttl=50 time=281 ms
64 bytes from 66.211.214.131: icmp_seq=2 ttl=50 time=201 ms
^C

Although, most programs just report "could not resolve host" rather than "system error".

Chromium works fine for some reason

Re: [SOLVED] Name resolution stopped working after upgrade

As suggested in the above link, removing 'wins' from /etc/nsswitch.conf solves it.

hosts: files mdns4_minimal [NOTFOUND=return] dns wins myHostName
