New Networking Issues

			Hey guys, A friend of mine in the dorms recently asked me to take a look at her WinXP machine. She’s having trouble connecting to the internet. The weird thing is that I can do an ipconfig release\renew without a problem. It also displays the connected icon in the bottom right corner. However, she can’t surf the net or use her connection at all. I tried a different working jack\cable, and I had the same results. My only guess is that either 1) she’s been blocked at some switch\firewall, or 2) there’s some issue with XP I’m missing. Thanks in advance.

			She's in the same dorms as you? Is anyone in the same wing having trouble. Maybe theres a hub or something that went down in that section?

			Just semi-random ideas, but it sounds like it may be one of: - It's not set up to use DHCP and release/renew is just resetting the interface. Go into the settings for the network adapter and make sure "Obtain an IP address automatically" (or some similar wording) is enabled. - The local network works but the connection to the internet is down. See if you can ping another box (e.g. the DHCP server). - The DHCP server is handing out the wrong address for some reason and a router is dropping your packets. - DHCP isn't actually being used and the wrong address is typed in.

			Hmmm, her room mate's machine works perfect. DHCP was in fact on, that's the first thing I checked. As far as router dropping packets, it's possible, but you would still have atleast some degree of usability. It would just appear to be incredibly slow. And it wouldn't drop just her packets, it would drop everyone's packets. Internet is working fine (see this post). The only other person to have a similar problem is her suitemate, she has had the same problem for about a month. I can't ping other boxes because I think it's blocked on a number of different levels. I did try telnetting to the main email server, that didn't work. I also tried telnetting to the ip of the main email server, that didn't work either (I think that ruled out DNS?). I'm really, really stumped on this. I emailed the network admin and sent her the girl's ip and mac, hopefully he'll be able to check if she's blocked or something.

Not if it's dropping all the packets because you were handed a bogus address...

			Maybe its an issue with the hardware/driver? Can you get it to talk to any box, even with a crossover cable 1 to 1?
