DHCP question

[huanaku]

My university provides ethernet. I have had it up and running for a year without problems. Two days ago, I got home from work and had lost my network connection. I figured the proxy was down, or a dhcp server was down. Anyway, everyone around me has a working connection. So I check my network settings, everything looks correct. For all I try, I cannot get an IP. I've tried on win98se, windows me, win2k server, win2k pro and get the same error:

DHCP server unreachable

What could be the problem?? I have tried different networks cables and different NIC's. The protocals are set-up correctly. I talked with our computers services group, and they said their server did not show a connection to the ethernet jack in my apartment, even though everything is plugged in. One weird thing--in win2k, I have the line speed set to "auto detect" and it detects the speed at 10 megabit. So I think there is some connection. My thoughts -- either the jack went bad, or the jack has been set to deny on some DHCP server. Any other thoughts? this is really confusing me.

You can try a couple things.

You probably know others in your dorm that have a connection to the network. I would go to a friends room, ask to use his system. He should have a IP address. Find a IP address on the same IP block (for example, if he has 192.168.1.5, ping 192.168.1.6 and so on) to see if it is being used. Find one that isn't being used and then go to your system and set up a static IP on that IP address. Try to ping your friends workstation from your system. If you can't ping it, then you are dealing with a jack problem.

I would assume that you might be looking at a hardware problem myself. It could be a jack in your room or maybe a cable? You can always take your computer down the hall to another jack and try it. If you get a address, then you know it is the connection in your room.

dhcp server is down your friend's internet connections are probably working because they cached the information, while your computer didnt

The DHCP servers are up, and mine does work in another room. I'm pretty sure the problem is in the jack. I talked with the support office and they show my jack as being active, but not having connectivity, even though everything is plugged in correctly.
