Check the ram modules as one or more of them could be faulty.

Testing software here:

1. Click "Download Pre-built and ISOs"

2. Click "Download - Pre-Compiled Bootable ISO (.zip)"

3. Unzip the download and use it to create a bootable CD.

4. Boot from the CD and run memtest. The longer you run it, the more chance it has of finding a ram fault if one exists.

Did you make a typo when you typed mininet.dll ?

Is the actual filename wininet.dll ?

If it IS mininet.dll, it's not a legitimate Windows file - that's a file name associated with malware.

If it's wininet.dll, that's a standard Windows XP file, and in your case it's probably been damaged, and needs to be replaced.


This is a module that contains many different internet functions, like all DLL's, many of them are used to share functions for various applications. In this case, Windows uses the wininet.dll for various internet related functions. For example, if you run Microsoft's anti-spyware program, you may see the wininet.dll appear in your startup list, as it may call this to perform a function during bootup time. (See the details below for the actual location of this file.)

This will be found in your system32 folder, at c:\windows\system32\ "

Note that at the first link above that if wininet.dll is NOT in c:\windows\system32, it can also be malware, if it's at any of the locations mentioned in that.

Boot into Safe mode.

Remove any bootable disks you have in drives.
Press F8 repeatedly while booting, don't hold down the key, and when the boot choices menu appears, choose Safe mode.
The screen will fill with lines about things that are loading, stay that way for a while, then your Logon screen will appear, or the desktop screen will appear in a short time if you don't need to Logon.
Answer Yes to running in Safe mode when the window appears about that.

Go to the C:\Windows\System32\dllcache folder.
Copy wininet.dll to the C:\Windows\System32 folder
You should not get the error anymore when you boot normally.

If you don't see the C:\Windows\System32\dllcache folder

Control Panel - Folder Options - View

Change Hidden files and folders to
Show system files and folders
by clicking on the circle beside Show system files and folders to insert a dot.

Click on the square box before Hide extensions for known file types to remove the checkmark.

Click on the square box before Hide protected operating system files to remove the checkmark.

Click on OK at the bottom of the window.

Then go to the C:\Windows\System32\dllcache folder,
copy wininet.dll to
the C:\Windows\System32 folder.

If Windows won't let you replace wininet.dll with the copy,

- if you can still run Windows in normal mode despite the error, you could run system file checker to replace it.

Start - Run - type: sfc /scannow (click OK or press Enter.
(a space between sfc and /scannow. )

It takes a long while to complete - e.g. at least a half hour or so.
It doesn't display any messages about whether it did anything - whether it replaced corrupted or missing files.
Restart the computer after it's finished.

If you still have the original brand name software installation on the computer and it had SP2 updates included originally, and if you have NOT installed SP3 updates, you won't need to insert an XP CD.

If you HAVE installed SP3 updates, system file checker will require you insert an XP CD that has SP3 updates included on it, otherwise sfc won't won't accept the CD as a valid source of files.

You can't quit sfc a normal way once it starts. Press the Alt-Ctrl-Del keys at the same time to pop up Task Manager, it will appear eventually, select Shut Down in the top bar, then Restart or Turn off.

- if you can't run Windows in normal mode after you get the error, or if you can but you can't use sfc, you're going to have to use some other method to replace wininet.dll.

E.g. If you have or can borrow a Microsoft XP CD, or you have the equivalent Recovery CD that came with the computer, e.g. an XP operating system installation CD, you can boot the computer with the CD then go into the Recovery Console after the initial files have loaded, by pressing R to go there.
(OR you sometimes have the option on the screen while booting an original brand name software installation of going to the Recovery Console by pressing a specified key. )

Type the number of the Windows installation, press enter.
Usually that's 1, press Enter
When you see .....Password, just press Enter.

Then go to the C:\Windows\System32\dllcache folder,
copy wininet.dll to
the C:\Windows\System32 folder.

The prompt will be at C:\Windows
cd System 32\dllcache (press Enter)
copy wininet.dll C:\Windows\System32\wininet.dll (press Enter)

( OR - Type
copy C:\Windows\System32\dllcache\wininet.dll C:\Windows\System32\wininet.dll (press Enter)
(all in one go ))

exit ( press Enter) , to exit the Recovery Console and restart the computer

I have ten wininet.dll files - five are the same largest size, roughly, three of them have the same newest date - 21/12/2009 - the newest version is in C:\Windows\System32 and is identical to the one in C:\Windows\System32\dllcache

In the unlikely case of......
If the wininet.dll in C:\Windows\System32\dllcache is malware, when you use that to replace the one in C:\Windows\System32 you may still get the error when you boot normally.

If so, copy the newest copy of wininet.dll that's on your harddrive, OTHER THAN the one in C:\Windows\System32\dllcache , to C:\Windows\System32, and if doing that gets rid of the error when you boot normally, copy the same wininet.dll to C:\Windows\System32\dllcache .

I have a copy of wininet.dll identical to the ones in C:\Windows\System32 and C:\Windows\System32\dllcache in
