NetworkManager sabotages DNS? on fc9

[Dave Burns]

I just installed fc9 on a Dell precision T5400 from the live CD. On
previous fc9 installs, I've had a problem that networking doesn't
start at boot if I didn't open up the network panel and check
"controlled by networkmanager". On this new install, when I have that
box checked, DNS does not work (nslookup times out). If I uncheck that
box and disable/enable eth0, DNS starts working. DNS is being served
to this machine from another machine.

Does NetworkManager get DNS info from DHCP or somewhere else? How
could this behavior make sense? Does NetworkManager assume dynamic
addressing? I am trying to make it static, could that be the problem?

I guess I will experiment with just turning NetworkManager off, since
this is a desktop unit not a laptop, has no wireless.

Thanks for clues,
Dave
