wshtcpip.dll file damaged and can not connect to internet

[Guest]

My girlfriend recently bought a dell inspiron 1520 laptop and it worked great
for the first couple weeks. However, Monday when she started the computer up
it gave her the error message "GoogleDesktop.exe - Bad Image -
C:\windows\system32\wshtcpip.dll is either not designed to run on Windows or
contains an error. Try installing..." Once closed, the same message came up
but for SiteAdv.exe (McAfee's Site Advisor). Additionally, the computer
would connect to the wireless network, but get a local connection only; no
internet.

Unistalling Google Desktop, and uninstalling/reinstalling McAfee made the
error messages go away, but did not solve the internet issue. I have reset
my modem and router several times and the internet works perfectly on our
other laptop and our old desktop. The internet does not work even if the new
Vista laptop is plugged directly into the modem. While trying to fix the
problem, I tried to ping microsoft.com in the command prompt and got a bad
image error again.

I tried running the StartUp Repair, but it keeps telling me to remove all
USB devices and memory cards even when none are plugged in. What else can I
do to solve this problem? Am I right in assuming that the damaged dll file
and my internet problem are connected (the name of the dll file and from what
little I have read about this file seems to suggest they are)? I greatly
appreciate any advice!

The file wshtcpip.dll is the Winsock2 Helper DLL.

You could see if the file is damaged by running the following command (by
right-clicking on the Command Prompt shortcut in Start
Menu\Programs\Accessories, and choosing Run as Administrator). Copy and
then Paste this at the prompt:

sfc /SCANFILE="C:\Windows\System32\wshtcpip.dll"

Press Enter on your keyboard. What does Windows Resource Protection report?

If you want check all your system files, Copy the following, and Paste it
after the prompt:

sfc /scannow

Press Enter. It will scan all your system files. It may take a few
minutes. If things are okay, you are given the text message "Windows
Resource Protection did not find any integrity violations". If things
aren't okay, it will attempt to replace the bad system files.
