Red Stop sign. What does it mean?

[Deborah0702]

I am getting a message that says

IP Configuration 192.***.0.4 in use by 00:23:32;58:d5:ea, DHCP Server 192.1**.0.1 there are numbers where the asteriks are. Does anyone know what this means?

Thanks in advance.

You are trying to run your computer with an IP address that's already in use on the network. Do you have your IP address fixed in the Network preferences?

It means you need to renew your IP address via the DHCP server. Another Mac is using the current IP.

It sounds like your IP's are colliding.

Most often this happens when 2 or more devices are being given the same IP address from the router via DHCP.

How is your network configured?

Woah triple threat! ----^^^^^^^^^

Turn off your router and turn it back on again, should fix your problem.

Im assuming you have a wireless computer somewhere on your network as this is usually what causes this particular problem.
