I just installed redhat 9.0 on a Dell sever. I selected �use DHCP� during installation.
Now it can not connect to my network.
It says �Determine IP failed� during startup at �bring up eth0� step.
Thanks.

Well, let's look at the obvious things first: is there a DHCP server on your network? Did the driver for your network card initialize OK?

Yes. I used to install Mantrake 8 on other PCs the same way. This time I am installing Redhat 9.0 on a Dell server box.

How to check this?
Thanks.

Use the "dmesg" command to see the messages printed during boot time; look for failures.
Other ideas: search in /var/log/messages for "dhcpcd" and see if you find any useful log messages that explain the problem. If not, stop dhcpcd with "sudo /sbin/dhcpcd -k" and start it again with "sudo /sbin/dhcpcd -d" so it will print debug messages, and you will get more useful data on stdout and in /var/log/messages.
To actually see the debug messages, you have to arrange to get them logged. From the dhcpcd man page:

By the way, why wouldn't you use static ip for your server?

Our network people figured this out by playing Network config.
dmesg is interesting command.
