Still no /etc/resolv entries.  I then did a 'ls -ls /etc/res*' and the file has not been touched for days!  So NetworkMangeler is sure that there is no reason to make any changes, dispite what it SHOULD be getting in the DHCP returns...

Are you using the GUI to configure?  Do you have the "method" set to Automatic or Addresses Only?

Check the interface scripts in /etc/sysconfig/network-scripts if PEERDNS=no then it only get IP addresses and not things like searchbase or dns servers.
