This error code occurs when the Dpcdll.dll file is missing or corrupted.

To work around this problem, replace the Dpcdll.dll file by using a clean Dpcdll.dll file that has the correct version.

Note To obtain the clean Dpcdll.dll file, copy the Dpcdll.dll file from a new installed computer.

This problem frequently occurs after you upgrade a service pack. After you upgrade, there appears to be a corrupted file, a missing file, or a file mismatch.

To work around this problem, uninstall the service pack that you installed. Then, reinstall the service pack.

This problem can occur if one of the following conditions is true:
The default security provider in Windows XP has changed.
The system drive letter has changed.

To work around this problem, use the appropriate method.
Reset the default security provider in Windows XP
To reset the default security provider in Windows XP, delete the relevant registry keys from the registry. To do this, follow these steps:
Start the computer. Press the F8 key during startup to start the computer in safe mode.
Click Start, click Run, type regedit, and then click OK.
Delete the following registry subkeys from the registry:

HKEY_USERS\.DEFAULT\Software\Microsoft\Cryptography\Providers

HKEY_USERS\S-1-5-20\Software\Microsoft\Cryptography\Providers
Exit Registry Editor.
Restart the computer.

Reset the drive letter of the system drive
Use Registry Editor to change the drive letter of the system drive back to its original value. Edit the following registry key to change the value of the system drive:
HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices
For more information about how to restore the system drive letter, click the following article number to view the article in the Microsoft Knowledge Base:
223188 How to restore the system/boot drive letter in Windows

This problem occurs if you modified the
MountedDevices
registry value to change the boot drive letter assignment or the system drive letter assignment.

To resolve this problem, you must remove the whole contents of the
MountedDevices
registry key. This key is located in the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices
For more information, click the following article number to view the article in the Microsoft Knowledge Base:
223188 How to change the system/boot drive letter in Windows 2000
You cannot modify the
MountedDevices
registry key in Windows XP because there are many hard-coded paths to the C:\Windows drive. These hard-coded paths may not load. Then, that behavior provokes the WPA-related error code.

This problem occurs because the drive letter has changed or because certain files cannot be found at default locations.

To work around this problem, use one of the following methods.

Note If the methods in this section are unsuitable for your situation, then use the methods in the “Workaround for an error code that is not in this list” section, and begin with Method 1.
Use Ghost
If you deploy a Windows XP-based computer by using Ghost from Symantec, rebuild the Ghost image by specifying the –FDSZ switch during the rebuild process.
Use Drive Image Pro
If you deploy the Windows XP-based computer by using Drive Image Pro, upgrade the Drive Image Pro to Deploy Center version 5.0 from Power Quest.

This problem may occur if a file that the Windows Product Activation (WPA) requires is damaged or missing. This behavior occurs if one or both of the following conditions are true:
A third-party backup utility or an antivirus program interferes with the installation of Windows XP.
A file that WPA requires is manually modified.

Method 1
Note You should follow this method if this error code occurs after you upgrade from Microsoft Windows 98 Second Edition.

Start from the Windows XP CD-ROM, and then perform an in-place upgrade repair. Make sure that you use a valid product key. For more information about performing an in-place upgrade, click the following article number to view the article in the Microsoft Knowledge Base:
315341 How to perform an in-place upgrade (reinstallation) of Windows XP
You can also resolve this problem by uninstalling Windows XP. Then, reinstall the operating system that you were running before you upgraded to Windows XP. For more information about how to uninstall Windows XP, click the following article number to view the article in the Microsoft Knowledge Base:
312569 How to manually start the uninstall process to remove Windows XP
Method 2
To resolve the problem, repair the installation of Windows XP by using the Windows XP CD, and then replace the files. To do this, follow these steps:
Insert the Windows XP CD in the CD drive or in the DVD drive.
Restart your computer.
When you receive the following message, press a key to start your computer from the Windows XP CD:
Press any key to start from CD
Note Your computer must be configured to start from the CD drive or from the DVD drive. For more information about how to configure your computer to start from the CD drive or from the DVD drive, see the documentation that came with your personal computer. Alternatively, contact the manufacturer.
When you receive the following message, press R to start the Recovery Console. This part of the Setup program prepares Windows XP to run on your computer.
To set up Windows XP now, press ENTER.

To repair a Windows XP installation by using Recovery Console, press R.

To exit Setup without installing Windows XP, press F3.
You see a numbered option, such as the following:
1. C:\WINDOWS
Note this path to Windows (In this example, the path is C:\WINDOWS) for later user in step 7 and step 11. Then, press 1 to access your primary drive installation by using the Recovery Console.
When you are prompted, type the administrator password. If you do not have an administrator password, press ENTER.
Type cd C:\WINDOWS\System32, and then press ENTER.
Note In this command, use the path that you noted in step 5 if it differs from C:\WINDOWS.
Rename the following files by using the REN command. To do this, type REN File_Name.extensionFile_Name.old at the command prompt.
Wpa.dbl
Pidgen.dll

Licdll.dll
Regwizc.dll
Licwmi.dll
Wpabaln.exe

Dpcdll.dll  (this one is founded by me)

oobe\Actshell.htm (Note This file is located in the oobe subfolder)
Note In the previous command, you must replace File_Name.extension with the file name from the list of files in this step. Additionally, File_Name.old represents the new name for the file name. For example, use the following command for the Wpa.dbl file:
REN Wpa.dbl Wpa.OLD
Type the drive letter of the CD drive together with a colon, and then press ENTER. For example, you type D:, and then press ENTER.
Type cd i386, and then press ENTER.
Type the following commands individually. Press ENTER after each command:
Expand licwmi.dl_ C:\WINDOWS\System32
Expand regwizc.dl_ C:\WINDOWS\System32
Expand licdll.dl_ C:\WINDOWS\System32
Expand wpabaln.ex_ C:\WINDOWS\System32
Expand wpa.db_ C:\WINDOWS\System32
Expand actshell.ht_ C:\WINDOWS\System32\oobe
Copy pidgen.dll C:\WINDOWS\System32

Expand dpcdll.dl_ C:\WINDOWS\System32
Note In these commands, use the path that you noted in step 5 if it differs from C:\WINDOWS.
Type Exit, and then press ENTER to restart the computer.

Attempting to delete them results in “Error Deleting File or Folder – Cannot delete file: Cannot read from the source file or disk“.

Note: Windows 7′s version of this message is something like:

Could not find this item: This is no longer located in C:\Blah. Verify the item’s location and try again.

Even going to the file’s properties to check permissions presented a very blank properties dialog. And a CHKDSK didn’t sort thing out either.

It turns out the problem was: the filename ended with a dot, e.g. it was something like “C:\Temp\Stuff\Sales Agreement.“. As far as Windows is concerned this is an invalid file name: so although it gets reported in a directory listing, the standard Windows APIs for manipulating files subsequently deny its existence.

So how did this file get created in the first place? The answer: a Mac. The file was on a file share which had been accessed by a Mac user. Macs tend to write all sorts of metadata to extra “._DSStore” files and suchlike and had left this file behind.

So if Windows doesn’t appear to allow these file names, how did they get to be created? Well, it turns out that NTFS allows all sort of file name/path weirdness that Windows, or specifically the Win32 API, doesn’t allow. For example, NTFS actually allows file paths up to 32K but Windows restricts file paths to no more than 260 characters (MAX_PATH). I suppose this is all for DOS/Windows 9x backwards compatibility. As these files were being accessed over a file share I guess the usual Win32 checks are bypassed.

But thankfully you can get Win32 to ignore these checks by prefixing your file paths with \\?\, (ie. C:\Temp\SomeFile.txt becomes \\?\C:\Temp\SomeFile.txt) which I discovered after reading this blog post about long paths in .NET.

So at a command prompt (Start > All Programs > Accessories > Command Prompt) I was able to delete the file using:
del “\\?\C:\Temp\Stuff\Sales Agreement.”

Note: On Windows 7 it seems you can just use wildcards without the \\?\ trick to delete the offending files: e.g.
del c:\temp\somefil*

If it’s a folder/directory you’re trying to delete use the rd or rmdir command, e.g.:
rd /s “\\?\C:\Documents and Settings\User\Desktop\Annoying Folder.”

Tip: as you’re typing the file/directory name use the TAB key to auto-complete the name (press TAB repeatedly to cycle through possible names).
