Connecting to Network

I am very new to Linux. I have installed RH 7.1 and I’m trying to connect it to my MS network. When I click the network icon on the kontrol panel it says “Couldn’t execute /usr/bin/kdesu “/sbin/netconf”. Please install the linuxconf package.”

From what I’ve read linuxconf package is automatically installed with RH 7.1. Why is this so?

I am using RTL8139C NIC.
Thanks in advance!
