DNS resolution not working in Build 9000

DNS resolution not working in Build 9000

I've recently updated to Build 9000 and have noticed that DNS resolution is no longer working.  I'm running on Ubuntu 10.4.  DNS resolution works on the machine the build is running on and I've not changed any default settings in the admin panel.  When I click 'resolve DNS', it looks like it 'tries' to, but then just shows the IPs again.

Anyone else seeing this problem?
