[SOLVED] Common Networking Issue - Completely Stumped

[DAndras6367]

Hello,

I am not completely new to Linux, but I definitely do not qualify myself as a guru. =)

I have read numerous threads here and elsewhere regarding similar situations, and I have tried just about everything to figure this out, to no avail.

We recently moved a server from New York to Florida and I am having an issue getting it to see our gateway device and other devices on the local network.

The following is a long list of information that I believe may help you help me. =P


ifcfg-eth0
DEVICE="eth0"
BOOTPROTO="dhcp"
IPV6INIT="yes"

Determining IP information for eth0... failed.

This is when I have the interface set to dhcp. However, if I change it to
static and assign ANY ip address (I ran nmap to check available ip addresses
on our network), it returns the following:
Error, some other host already uses address 192.168.1.94.

If there is anything else that I could provide you with I will be more than happy to!

Thanks in advance!
