CentOS 5.6 - IP Networking Issue

[latinrx]

Good afternoon,

I'm trying to run CentOS 5.6 in VirtualBox on a Windows Server installation (Dedicated box, not a VPS). I'm able to get Cent to install just fine, it works great except for the networking aspects. When it starts up it says error, some other host already uses 192.168.100.3. There are no other devices on the network using that IP address. When I start up Ubuntu, it is able to use that static ip setting just fine. I've got CentOS on many other boxes, just not running in a virtual setup. Does anyone have any ideas?

Thanks,

-Nate

Well, when i manually set the gateway ip in the command line, and use ifconfig to manually set the static ip, ipv4 stuff seems to work fine. I wonder why Cent is having trouble on startup? Any ideas? Thanks in advance by the way.

Turn the VM off, then ping that IP from the Host. Do you get a reply? If not, then check the network configuration of CentOS, it might have the configuration twice and misinterprets it.

Hey sasquatch. No reply on ping with the VM off. In /etc/sysconfig/network-scripts/ifcfg-eth0, the settings are the way they should be. Is there another location I should check?

Are there other ifcfg-* scripts there? Do any of those have the same IP?
