Problem on Redhat Linux: RealTek RTL8169/8110 Family Gigabit Ethernet NIC: eth0 not

[sahidul]

I am unable to configure network ethernet: eth0 on Redhat Linux 5 on HP desktop (64 bit) with RealTek RTL8169/8110 Family Gigabit Ethernet NIC.

In windows, the network is working fine. but
while configuring network in Redhat i.e., Ethernet port, it is giving errors like: Initialization failed..... not found eth0 .

Please help me to sort it out.

Thanks in advance
