You should also add netmask and gateway and DNS entries into the NM applet.

I have done this with complete success, and here is what happens:

I turn on the system from a cold start.  NM is doing its thing or 
already has -- I LEFT click the applet and choose my work config.  Poof, 
all is well.

Yes, I need to do that every time the system boot at work, but my main 
system is a laptop, and so it is appropriate that I run NM.

If you are NOT a laptop, then please, please follow the advice already 
given and simply revert to NM off and network services on.

If you really want to make NM do all the right things, then tell it so 
in /etc/sysconfig/network-scripts/ifcfg-eth[0-N].  Those files will 
always have precedence, and you can even tell NM to just use these files 
as is.  You can put DNS in there too, so that network services will 
create for you exactly the resolv.conf you want.

You may have noticed that there are now two network administration 
applications: Network -- Network Device Control

Network is the old one, and is used with the old network scripts.  
Network Device Control understands the additional syntax for the ifcfg 
scripts to work with Network Manager.  Give that one a play and see what 
it does to the config files: /etc/sysconfig/network-scripts/ifcfg-eth[0-N]

Good Luck!
