Could Not Connect To Internet - "bad Checksum" ?
Jul 29, 2005
I have a Dell Dimension 2400 with a US Robotics 56K PCI fax modem, which I've used over a month with no problem. Yesterday I dialed-up a connection to isp.When I tried to update Microsoft Antispyware, it said "could not connect to internet" Spybot S&D said "bad checksum" Could not download e-mail, although it was said it was receiving. "Timed out" when tried to go to web site, messages like "google could not be found", "page cannot be displayed", etc. FoxFire home page blank. System restore to 7-26 seemed to remove problems, but some soon returned. Again system restore to 7-26.

I was attempting to reformat a Dell Inspiron 8000 with XP Home and have received the following message:
STOP: C0000221 {Bad Image Checksum}
The image olethk32.dll is possibly corrupt. The header checksum does not match the computed checksum.
This PC will not even boot from a Windows 98 boot disk.

I'm setting up my friends home network. They have 2 PCs connected via ethernet and one laptop on wireless. The router is a wireless router / modem from 2wire. PC number 2 and the laptop both connect with no issues. PC number 1 is weird though. I can go to 192.168.1.254 and it opens up the router system page and I can go through and change and view settings. However when I try to go to any websites it immediately goes to "Internet Explorer cannot display the webpage." I have tried netscape and the iTunes store and nothing can connect to the web. I have linux ubuntu on a Live CD and I can boot from that and it connects to the internet just fine.

After long periods of my internet connection being idle (2+ hours usually), all programs requiring internet access are unable to connect. By idle I mean I leave to run some errands with no programs other than Zone Alarm running. My DSL modem still has all lights flashing and active. There are a couple other scenarios where this occurs as well. Ex. I'm playing WoW for extended periods but not using the internet through any other program, then upon alt-tabbing no other applications are able to connect to the internet even though WoW is still connected and functioning. Rebooting the router/modem doesn't fix it, but rebooting the comp does.

Because of many crashes and a Windows messages telling me my BIOS was probably out of date I updated it through the Micro Star International.MSI Live Update Online. During the download process it gives you the option to backup your existing BIOS settings to a floppy. I don't have one so had to bypass. It seemed to worked but when the operation restarted I didn't know what I was supposed to do. In any case it rebooted but on that startup screen it said 'Checksum bad'. When XP loaded I got the 'the system has recovered from a serious error' message again. I thought that I must have done something wrong. I went throught the whole process again to update the BIOS process. XP loaded OK and everything seeme to work. Becasue of the previous problems I thought I had better check and restarted. I tried Pause/Break to freeze the startup screen bit by bit. But I couldn't grab the last line even with multiple attempts. No matter howm many times I tried I just couldn't read the last line,which I think said something about the Checksum' But couldn't make out whether it was bad or good. In previous viewings when it was 'bad' it was slower. Can anyone explain what is happening or how to capture the last line of text.

I am on a cable modem running W2K pro sp2 on a Dell 4400. My cable modem checks out OK as well as my ethernet card. There are no viruses or spyware in the computer as I checked that today. I've been thru level 2 tech support with my ISP and they are saying that the problem lies within the computer. When I open my browser I get the error msg page cannot be displayed and I cannot access any web page

I have Windows XP SP3 and I did some updates two days ago: I allowed a java update that was hanging around in my lower tray for a couple weeks, updated my adobe to the latest version and I updated to Internet Explorer 8. After having IE8 for less than 24 hrs, my husband and daughter said they didn't like it, so I did a system restore to three days ago and now I can't connect to the internet at all. From the small amount of research I've been able to do here at work, it seems that once you download IE 8 you can't revert back to a previous version? Could anyone tell me if that's true? I can't even open the internet options tab from the control panel to see if there is a settings problem.

Upstairs, I have a desktop and a laptop. They are connected to my wife's computer, downstairs, via wireless. Both my wife's downstairs computer and my laptop, upstairs, will connect to the internet just fine, but the desktop will not, even though it shows that there is a strong signal being received. I am running Windows XP Pro, version 2002, with SP2. The computer has an AMD Athlon chip. It used to be a Tiny computer, but after having a major meltdown, about two years ago, I took it to a repair shop, and they installed an ASRock I/O K7S41/K7S41GX motherboard, as well as a new power supply, so I don't really know what to call my computer, now. I guess it's just sort of a mongrel, Heinz 57 Variety.
I have tried using System Restore, but it won't allow me to restore to a former point, no matter how far back in time I go. I started it up in safe mode, then ran AVG, but no viruses were found. When I go to Control Panel, then "Network Connections," it shows that the wireless network is up and running. Even so, I tried repairing the network, by right-clicking on "Repair," but got the following message: "Windows could not finish repairing the problem, because the following action could not be completed: Failed to query TCP/IP settings of the connection. Cannot proceed. For assistance, contact the person who manages your network." Unfortunately, that person is me, who is totally clueless

My son was just using his computer last week, it was working fine. He goes to use it the following day and he cannot connect to the internet. We have multiple laptops in our home along with a desktop. We all can connect just fine. We can't figure out what is going on with his. I've tried to reboot,we've tried connecting to the hard line, we've checked out the wireless router and the signal is fine. We've played with everything that we can play with and nothing works?

I just got hit by a trojan that attempts to download malware. My virus protection stopped all the downloads and I was able to manually remove the trojan, but I'm concerned I may have missed something. Three times in the last couple of days, I have discovered the dialer on my computer open like some application was trying to connect to the internet.

I am trying to set up an internet connection via a dial-up modem. When I go to my Connection Wizard and follow through the steps I get to the section to "Connect using a dial-up modem" but it is GREYED OUT. The one directly below it is greyed out as well. Can anyone help with this? Been trying everything for the past few weeks but nothing works. Need to get my connection moving in order to start university courses.
