Problem description

On a computer that is running Windows XP, Windows Vista or Windows Server 2008, you have a folder that is encrypted by using Encrypting File System (EFS). You upload the files in the encrypted folder to a Web Distributed Authoring and Versioning (WebDAV) share folder. The files that are uploaded to the WebDAV share folder remain encrypted.

In this case, you may want the encrypted files to be decrypted during the file copy operation to the WebDAV share folder so that other users have access to the files. However, you cannot find a method to disable EFS encryption during the WebDAV file copy operation. This article helps you fix this problem.

Cause

This problem occurs because Windows XP, Windows Vista and Windows Server 2008 WebDAV clients maintain encryption information for secure file copy and storage operations.

Resolution

A hotfix is available to resolve this problem. After you apply this hotfix, you have to change the registry to enable the hotfix. For more information, see the "Registry Information" section.

After you enable this hotfix, you see the following changes:

  • If you copy an encrypted file to a WebDAV share folder that is not encrypted, you are prompted that the encryption on the file will be removed if you continue with the file copy operation.

  • You cannot encrypt a file or a folder in a WebDAV share folder. This change is made by hiding the Advanced tab on the Properties page of a file or of a folder.

    Note This change only applies to WebDAV share locations.

  • If you copy an encrypted file to an encrypted folder on the WebDAV share folder, or if you overwrite an existing encrypted file on the WebDAV share folder, the file remains encrypted.

Hotfix information

A supported hotfix is available from Microsoft. However, this hotfix is intended to correct only the problem that is described in this article. Apply this hotfix only to systems that are experiencing this specific problem.

If the hotfix is available for download, there is a "Hotfix download available" section at the top of this Knowledge Base article. If this section does not appear, submit a request to Microsoft Customer Service and Support to obtain the hotfix.

http://support.microsoft.com/contactus/?ws=supportNote The "Hotfix download available" form displays the languages for which the hotfix is available. If you do not see your language, it is because a hotfix is not available for that language.

Important Windows Vista and Windows Server 2008 hotfixes are included in the same packages. However, only one of these products may be listed on the “Hotfix Request” page. To request the hotfix package that applies to both Windows Vista and Windows Server 2008, just select the product that is listed on the page.

To apply the Windows Vista-based hotfix, you must have Windows Vista Service Pack 1 installed on the computer. To apply the Windows Server 2008-based hotfix, you must be running Windows Server 2008 on the computer.

Restart requirement

You have to restart the computer after you apply this hotfix.
