Although this error code occurs mostly on Dell computers it can occur on other brands of computers as well. The problem is caused by any type of software which can alter the default security provider in Windows XP or a system drive letter which has been changed for unexplained reasons. In order to resolve this issue it is necessary to edit your PC’s registry. For this reason it is important to backup your registry before proceeding to fix the problem.

First you can begin by resetting the default security provider for Windows XP. To do this you must eliminate the registry keys which are associated with the security provider. Begin with your PC completely shut down and then boot up the PC. During the boot process press the F8 key to start your PC in Safe Mode. Click on Starton your main toolbar and then choose Run. When the Command Prompt appears type in regedt32.exe and then click OK. When the Registry Editor window opens, double click on the HKEY_USERS folder and then click on the .DEFAULT folder. Choose the Software folder and then click on the Microsoft folder. In the Microsoft folder choose Cryptography and then click on Providers. Right click on the file HKEY_USERS\.DEFAULT\Software\Microsoft\Cryptography\Providers and delete it. Follow the exact same procedure again except follow this file path HKEY_USERS\S-1-5 20\Software\Microsoft\Cryptography\Providers.Close the Registry Editor and then restart your PC in normal mode.

If the drive letter has been changed on your system you must be very careful when performing this task so if you are not comfortable you may want to enlist the help of a professional PC repair person. That said you can change the drive letter of the system back by clicking on Starton your main toolbar and then choose Run. When the Command Prompt appears type in regedt32.exe and then click OK. When the Registry Editor window opens, double click on the HKEY_LOCAL_MACHINE folder and then click on the SYSTEM folder. Choose the Mounted Devices folderand then right click on the folder and choose Permissions to verify that Administrators have full control.
