Comment 38 for bug 93360

I can confirm this issue on Gusty 2.6.22-14-generic with a wireless connection.
Just upgraded to Gusty from Feisty. A snip from /var/log/messages:
Oct 24 21:01:40 AMD-XP-1700 dhcdbd: message_handler: message handler not found under /com/redhat/dhcp/wlan0 for sub-path wlan0.dbus.get.nis_domain
Oct 24 21:01:40 AMD-XP-1700 dhcdbd: message_handler: message handler not found under /com/redhat/dhcp/wlan0 for sub-path wlan0.dbus.get.nis_servers

I don't know if this is what is causing my problem, but it seems that randomly I can not resolve domain names.
This seems to happen if I'm checking for package updates. The following output is from before checking for updates:
$ ping google.com
PING google.com (72.14.207.99) 56(84) bytes of data.

rtt min/avg/max/mdev = 107.003/107.332/107.663/0.341 ms

And after checking for updates, which by the way fails, I get the following:
$ date && ping google.com

ping: unknown host google.com
$ date && ping -c4 72.14.207.99

So somehow something is triggering domain name lookup to fail.

By the way, restarting NetworkManager solves the problem temporary.

Any one got a similar problem?
