f8: network manager shuts down network on logout

[Nataraj]

I have an f8 system installed on a laptop.  It does not bring up the
network interface until I login on the X console and then shuts the
network back down when I logout.  f9 on the same laptop does not do
this.  How can I disable this function in f8 so that the network comes
up at boot and stays up (so I can remotely access the machine) unless I
tell it to reinitialize the network.

Thanks,
Nataraj
