hi all, i just did a "move" for my company from one building to another.

all the equipment worked before the move but now i can't get a PC running XP onto the internet.

i plug a network cable into the back of the problem pc and it tells me a LAN connection is now connected 100mbps.
but that pc won't go onto the internet regardless of the network cable i'm using.
i am able to get onto the internet with the other pc (also on XP) in the room.
i've also tried swapping network cables.
the hub i'm using has many computers attached to it and my problem PC is the only "problem."

what do i do or change to get this (bad) pc onto the internet?

and always, thanx in advance...

EDIT: one clue that might helps is the other (good) pc shows a message of LAN connection is now connected 1.0Gbps
is the difference of 100mbps and 1.0gbps the problem or just a symptom?

Just to doublecheck: Does it have gigabit networking or, megabit built in? Are there two network ports on the computer (i.e. one on the Mobo backpanel next to the USB, and another on a separate card)?

Is the problem PC getting an I.P. Address via DHCP or, a fixed I.P. address?

What equipment is performing DHCP services? Is there a server, or a router performing this service?

ping google.com see if you get a response. If yes, it is a pc only issue, if no then it is network related.

Can it get to other servers?

PC - check IE for proxy settings
Network - check the IP to make sure you have a valid address

Just throwing an idea out there but some ISPs limit the devices you can connect and will not register a different computer once you switch it in. At my last job I was responsible for a lot of troubleshooting computers for customers (despite my total lack of training or certification) and I ran into this problem a lot with computers using cable connections and a quick call to the ISP would correct it. It took me forever to figure out since I'd have no problem getting online hooking it up on the bench but once it was back at the customer's house it wouldn't work.

XP might either not have 1.0 Gbps full duplex or your auto negotiation is incorrectly detecting the speed.
In XP's Control Panel(Networks IIRC) Right click on your network adapter -> Properties -> Click Config button -> Advance Tab -> Link Speed and Duplex.
I would try to force the speed to 1.0 Gbps Full Duplex option if it is on auto negotiation. See if you have internet.

Could also be a IPV6 vs V4 issues if you switched routers

wow, thanx for the good replies...

i'll post up if i can figure this out!

i could not ping google.com and no matter what combination of cables i use, i can not get on the internet.
it can see hotfolders on other computers, though.

the other computers in the room are fine and work as you'd expect.

So, if you can communicate with other computers on your network it sounds like you're getting an IP address. Would be helpful if you could answer the questions we've had though.

Assuming that your computer is configured for DHCP, and is getting an IP address then it's most likely your router / network firewall that is not allowing communications with the internet.

do a start -> run -> cmd
type "ipconfig /all" and hit enter

if the "DHCP Server" has an address then you're getting the IP info from DHCP. If not, it's hard coded on the NIC and something is probably not right.

make sure you have a valid IP address
make sure the subnet mask matches a working machine
make sure the DNS server is correct

1 -
Next, try to ping another machine's IP address that is plugged into the same switch.
open a cmd
type "ping 123.2.2.2" (where the IP is a real IP address of a machine that's plugged into the same switch
Success = you have a valid IP and working Cable / NIC (go to step 2)
Fail = You have an issue on the local machine (need more info)

2-
open a cmd prompt
type "nslookup"
You should see your DNS server name and IP address. If it times out you have a DNS configuration issue
If you get there, try looking up Google

> www.google.com
Server: your.dns.server.name
Address: 123.234.123.2

Non-authoritative answer:
Name: www.google.com
Addresses: 74.125.225.212, 74.125.225.210, 74.125.225.211, 74.125.225.209
74.125.225.208

Post some results....

yes, the bad PC has it's own IP address.

I will work on getting the other answers tomorrow.

thanx for the helpful replies...
