I have a fun one ...
I have a Dell Inspiron e1505 running windows xp (sp2).
It has:
Broadcom 440x 10/100 integrated controller
Intel Pro/Wireless 3945 ABG Network card
and a 1345(?) Network integrated controller
Everything was working great on it until Tuesday night ... after a brief cut in service from my isp, the computer will no longer log on to the internet in normal mode. It will, however, work in safe mode + networking (the network integrated controller card does not appear in safemode, so I am not sure of the specs). In normal mode, it will ping itself and loop feedback ping, but it will not ping the dns. The computer actually shows as connected to the internet, but no internet browser will work.
Here's what I have tried so far (with help from it advisor from isp):
* attempted both static ip address and "automatically assigned" ip address
* edited the registry
* flushed the dns
* uninstalled and reinstalled all network cards
* scanned using adaware, spybot, and mcafee virus suite
* three system restores to points when the computer was definitely working
* disabled the wireless card and connected using ethernet
* disabled both the wireless card and the network integrated controller
Incidentally, the home hub seems to be working fine since my wife's mac will access the internet as normal. Also, my dell will access via the safemode method. The same problem with internet access occurs on other networks as well.
One other potentially unrelated problem ... at the same time the "mouse" (synaptics device) quit allowing the normal scrolling mechanism to work. Unsure if this could at all be related.
ANY HELP WOULD BE GREAT!!

Try turning off your firewall (software & momentarily) & see if you can connect
Another thing you can try is running MSCONFIG & turning off everything reboot and see if you connect...again momentarily

I'm confused. How many different networks cards are we dealing here and of what type? Can you ping your gateway? If so, it's a DNS problem. If not, it's a routing problem.
What's the output from ipconfig /all from a command prompt?

In reply to Deo Gratis:
I have tried both of your suggestions ... results, nil.
The firewall did not effect the link and I have now been through all aspects of msconfig ... the only way I can get the computer to link to any other server/computer/etc. is in safe mode.
In reply to rob pomeroy:
there are three different cards listed in the device manager (the broadcom manages the ethernet connections), the intel is the wireless card, and the other is the 1394 network integrated controller (I checked the numbers for this post).
In regular mode, I cannot ping the gateway or anything other than my computer. In safe mode, I can ping everything.
The ipconfig /all looks normal in both modes (in fact, it looks the same), giving the static ip address that has been assigned to the computer and the correct dns and gateway for the network I connect to at the time (either the library or home).
Thanks!

C'm'on - give us a bit more than that! :)
What's the output from ipconfig /all from a command prompt?
i.e. cut and paste it here, please.

Here is the ipconfig /all output when using the wireless card (I don't have access to ethernet at the time, but the ip address, gateway, and dns would be the same as the wireless since the it advisor from my isp set these as static on both ethernet and wireless):
windows ip configuration

when i ping the ip address, all packets are received. when i ping the default gateway and/or the dns server ... the host is unreachable. this is true in both ethernet lan or wireless.

You don't want the NIC and wireless card to be set to the same IP address. What TCP/IP settings are showing on your wife's Mac, out of interest?
I think you may have been led a little astray by your ISP here. Both of those IP addresses are public, which is wrong. On your LAN you should be using one of the Class A, B or C networks (see the networking FAQ - link is in my signature). Those settings may be appropriate on your router but are incorrect on your PC.
I'm not questioning your veracity, but would you mind also posting the safe mode output of ipconfig /all? I would just like to give it a second scrutiny, if you know what I mean.
-
PS 163.1.121.111 is from Oxford University's public IP pool. If OU is publically exposing the IP addresses of it' workstations, then the sysadm should be taken out and shot immediately. ;D But I doubt that's how things are configured.

I still did not have access to an wired connection ... thus, i only have the wireless ip information. At this point in safe mode, the computer will not connect to the internet at all (i had not tried using wireless in safe mode prior to this attempt).
-
What router do you have? Can you switch off your wireless and connect with an ethernet cable?
-
i have a bt home hub, and i can connect with an ethernet in safe mode. (at least, i could the last time i tried)
-
Do you know the IP address of the BT Home Hub?
-
According to my wife's macbook, the router's address is 192.168.1.254
her configuration is as follows:
ip address: 192.168.1.65
subnet mask: 255.255.255.0
router: 192.168.1.254
-
There you are then; your computer's IP address settings are incorrect. Configure the address manually (switch off DHCP) with the following settings:
NETWORK CARD
IP address: 192.168.1.66
Subnet mask: 255.255.255.0
Gateway: 192.168.1.254
WIRELESS CARD
IP address: 192.168.1.67
Subnet mask: 255.255.255.0
Gateway: 192.168.1.254
Try that and let us know if it works.

I'm not at home right now, so I can't (yet) try the ipconfiguration suggested above. However, I am at my office at school and am still having the same troubles. I can connect in safe mode + networking, but not in regular mode. The interesting thing is that the ipconfig /all looks exactly like my first ipconfig posting (with the exception being I am connecting via ethernet wire ... so the ip address is on that device rather than the wireless card) in BOTH safe mode and regular mode. It seems that something is blocking the regular mode system from connecting ... but I can't for the life of me figure out what.
-
when i tried the ip configuration you suggested, the same thing happened. it works in safe mode but not in regular mode. ugh!
-
same thing happens at home ... even with the new tcp/ip configuration. it will get on in safe mode, but not in regular. it won't ping anything except itself in regular mode.

FUBAR?
Sounds like there's an underlying problem here which is difficult to diagnose, long distance.
Reformat, reinstall. It is very purifying...
Have you read the networking FAQ, by the way? You do appreciate that your TCP/IP settings in the office will be different from your settings at home? Unless you live on the OU campus, you aren't going to be using OU IP settings at home for example.
