    Bad Image Checksum (XP Pro)

    On startup I get a normal splash screen then a Blue Screen of Death with the message STOP: c0000221 {Bad Image Checksum}
    The image wininet.dll is possibly corrupt. The header checksum does not match the computed checksum.
    Unfortunately none of the alternative startups give me anything different, I haven't been able to find my boot CD, and the manufacturer's (Toshiba) CDs seem to want to re-install everything. I haven't sought their help yet, but thought I'd ask for suggestions here first.

    Peter,

    You have a corrupt wininet.dll system file.
    Get a new copy of it HERE

    Do a search for that filename, note where each occurance of it appears and copy the new file over the old one.

    Also refer to MSKB 314474 for more detailed info.

    Today it is called golf!

    Thanks Bob,

    I have two computers, and the one I'm using seems OK (except for crashes when I try to install the recent Windows updates), and the version I have of wininet.dll on this is double the size and eight years more recent than the source you suggested. I am, however, left with the problem that I can't get beyond the blue screen to make any file changes. I may be able to boot from CD and do it, and I wonder if I could create a boot CD on this machine, which is XP Home, and use it on the other, which is XP Pro. I sure don't feel like re-installing Windows (and I'm a bit suspicious of women named George, although her advice seems OK).

    You lost me with the George bit?

    At any rate, try this copy of wininet.dll at HERE

    The boot CD should work, as long as you just want to get to a prompt, not a reinstall.

    Re: Bad Image Checksum (XP Pro)

    Sad to say, I still have the problem of having a machine that has now become a paperweight (although the delay in my posting back involved other matters). KB326687 sounds close but doesn't quite hit it, and the remedies are drastic.

    All I'd like to be do is delete the offending file if it isn't required for booting, then replace it with a copy from another machine if I can get the computer to boot or otherwise get through the blue screen barrier. There is an administrator password. One source has told me that a bootable CD can be made with certain burning software such as Alcohol-Software, CD-Mate, NTI, Stomp, and Nero, but that isn't much help once the machine is down (unless it can be done on a different machine and applied to the portable, in which case I might be able to arrange it).

    I sure don't feel like formatting the drive and installing everything from scratch. The manufacturer's help line was no help at all: does anyone think it would be a good bet to try their shop? All suggestions are welcome.

    Hi Peter,

    Have you tried to get the second copy of wininet.dll that I mentioned in <post#=366430>post 366430</post#> ?
    That should be a more recent copy of it and of the right size.
    If you can get it and copy it to a floppy ( if your machine has a floppy drive ) Then you can use ANY boot disk even Win98 or something to get you to a DOS prompt. Drill down to the C:Windowssystem32 folder and then copy the new file over the old. IF that's all that wrong, then you are home free.
    IF not, I would search high and low for the Windows XP CD and do a reinstall.
