Security Problem

[flamesword]

I have about 16 Linux machines and 2 windows machines on my network. Today i moved my PDC (Server 2003) to another location in the room wich means on the other side of a couple of switches. I had to move some other stuff do to space. When i moved everything around all my connections for my Linux machines have some security error. Basically my network cards will not pull DHCP address any more. I never moved the Linux machines but i did move the server and my Windows machines. All my windows boxes are working fine but none of my Linux boxes are (Core 13) Anyone have any possible solutions?

Since you're talking about physically moving computers and the effect that causes on networking, I have to assume you are talking about wireless networking. So it sounds like the problem is that you have 18 wireless computers competing for connections in a small space. That sounds like an RF or radio interference problem, not a networking problem.

If you shutdown all machines but one (or disable their wireless adapters) can it connect? If you rotate through all the machines, can they each connect by themselves?

Actually, a better question would be, can you use connect any of them with a physical cable instead of wireless?
