Network Manager is pretty much a justifiable suspect for hair loss,
weight gain, or why your car is suddenly getting really poor gas
mileage.

Stop any NetworkManager* services that may be running. Use chkconfig to
make sure they will not fire up at reboot. Use system-config-network to
configure and fire up your networking. Have a look
in /etc/sysconfig/network-scripts/ifcfg-eth0 to verify that onboot=yes

This should take of things, one would hope.

Oh, and yes, it's quite safe to uninstall NM.
