Yep, it's a NetBIOS name resolution problem in all likelihood.
Can you post the output of
ipconfig /all so we can take a look at the way the machine is set up to resolve NetBIOS names? To do that, open a cmd.exe window (Start/Run cmd.exe), and type the "ipconfig" command shown above. Then, with the left mouse button held down, select all the output that results. Click the right mouse button, which will copy the output to the Clipboard. Then paste the output into a reply.
If you can ping an IP address with no problems, but cannot ping a name like Dell.com it sounds to me like the DNS is down. You may want to contact the provider, or school to see if this is the case.
Actually, here are my settings with my machine WORKING PROPERLY (I did system restore)... If my machine is F'd up tonight after I return from school, I will post the new stats.
C:\Documents and Settings\Administrator>ipconfig /all
You need to go to Services and put DHCP Client and/ or DNS Client on automatic and started. If you on a LAN it is best with XP to enable netbios over TCP/IP it is in advanced>wins in the tcp/ip properties of your card.
Either rightclick your My Computer icon and click on Manage or go to the run box and type services.msc When you get there doubleclick the dns an dhcp this will get you to the properties to change everything.
I was referring to the fact that you couldn't resolve the name when you ping. Just added the netbios over TCP/IP info for networking .

I wonder if that means that NetBIOS over TCP isn't enabled for that connection?
Unless all the other machines on your home network are Windows 2000 or later, you'll need NetBIOS over TCP enabled for LAN name resolution to work. Even if they are Win2K or later, it may well be that browsing still needs it. I've never tried to run a Windows network (file/print sharing) without NetBIOS over TCP, so I don't know whether everything actually works without it.
AHA! The school's DHCP server is setting the NetBIOS node type so a WINS server is
required before Windows Networking will be able to browse for other machines! It's a good way of cutting down on broadcast traffic, but it will stop a laptop that's taken home from finding anything on the home network, since there's no WINS server to query!
The nicest change would be to have the school's network administrators change the NetBIOS node type from "peer-to-peer" to "hybrid". That setting causes a WINS server to be queried if one's available, and, if not, uses the "broadcast" method to resolve names. That would make their laptop users
very happy, because their laptops would then work correctly on both the school's (WINS server based) network, and on their home networks (no WINS server available).
The second nicest change would be if all DHCP servers supported sending the "NetBIOS node type" option. None of the SOHO routers that I'm aware of support that option.
Do you think there's any chance that the school's network administrators can be persuaded to make that change? If not, the only alternative (short of getting a home DHCP server that supports it!) is to "hack" the registry and force the connection setting to be "Hybrid" if it's not otherwise set via DHCP.
All I have handy in some notes: Actually mine says Unknown if I ipconfig /all, but if I use Wntipcfg it says Broadcast. I have no problems printing or sharing on my network using the info in my other thread. I have no alternate connection to try.
Run "ipconfig /all" on XP and look at the "Node Type" at the beginning of the output. If it says "Peer-to-Peer" (which should actually be "Point-to-Point") that's the problem. It means that the computer only uses a WINS server, which isn't available on a peer-to-peer network for NetBIOS name resolution.
If that's the case, run the registry editor, open this key:
If that doesn't fix it, open that registry key again, create a DWORD value called "NodeType", and set it to 1 for "Broadcast" or 4 for "Mixed". Above links explain better.
I don't know if they will change thing here for one person... Is there anything I can do to my mahcine/network/router so this doesn't keep happening?
I suspect you're not the only person with the problem. You may be the first person to know what the problem is, though. People don't tend to get the administrators of their work/school networks involved in home network problems. It took
exactly one report of the problem to convince me to make the change I described on a company DHCP server, because I knew that anyone else with a home net would be having the same problem.
Which router do you have? I'll check and see if the option exists on it.
So when I go home, what do I do to set my laptop to work properly?
I'll have to work on that. I changed a DHCP server configuration from "peer-to-peer" to "hybrid" last time this happened. I gather you think it's unlikely that the school will make that change.

I'll post my ipconfig info tonight when I return home.
Thanks.

There's one entry that's odd-looking:

I wonder if that means that NetBIOS over TCP isn't enabled for that connection?

You do realize the above-posted stats are from my machine while it is properly working... I will post stats later if it continues to be goofy.

I have to go to class now... A quick search did turn this up... Check the reg. edit on the first page... Is that applicable?

and delete these values if they're present:

DhcpNodeType
Reboot, then try network access again.
If that doesn't fix it, open that registry key again, create a DWORD
value called "NodeType", and set it to 1 for "Broadcast" or 4 for
"Mixed".
