Can't restore network after ifconfig down

I am using RedHat Linux 9 (Intel) and when I use the command ifconfig
eth0 down, I cannot restore my network. I tried ifconfig eth0 up, and
that didn't work.
When I try to use ping I get "Network is unreachable".

What do I need to do in order to restore network functionality?

Is there any error message provided when you try to bring up the
network, either on the console or in /var/log/messages? What does the
ifconfig -a show before and after the failure. how about route -n
before and after?

does service network restart work?

you can use ervice network stop/start to dis/enable your network.

You may need to rmmod your ether0's module. Check /etc/modules.conf
to see which module it uses. Normally I do this to revive it:
ifdown eth0
rmmod eth0's module
ifup eth0

Yes! Using the service command does the trick. Thanks a lot!
