LinuxQuestions.org - Network Card not detected when installing RHEL 5

Hi i have below average knowledge of linux. I installed red hat linux enterprise 5 as dual boot with windows. After installation when i tried to setup networking i found that it has not detected my RealTek Semiconductor RTL8168B/8111B PCI-E Gigabit Ethernet Adapter card.
