When we try to restore files and folders for a client connected to Windows Server 2012 R2 Essentials or Windows Server 2012 using dashboard, the “Restore Files and Folders” Wizard stops functioning as shown below.

In the Event Viewer, we get the following errors in the Application Log:

In addition to the event viewer we get an exception in the MountBackupWizard.log on the client computer, this log is present in C:\ProgramData\Microsoft\Windows Server\Logs folder:

An exception of type 'Type: Microsoft.WindowsServerSolutions.DataProtection.PCBackup.ObjectModel.PCBackupClientProviderException, BackupClientProvider, Version=6.3.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' has occurred.
Timestamp: 02/26/2015 08:07:15
Message: Exception of type 'Microsoft.WindowsServerSolutions.DataProtection.PCBackup.ObjectModel.PCBackupClientProviderException' was thrown.

 Workaround: As a workaround we can uninstall the Security Update from the client.

On a Windows 8.1 Client:

Run the command: Get-Hotfix -Id KB3023562
If the hotfix is installed, we will get information with all the details of the Hotfix.
Uninstall the hotfix (you may be prompted to restart the client computer).

On a Windows 8.0 Client:

Run the command: Get-Hotfix -Id KB3023562, KB3004375
If the hotfixes are installed, we will get information with all the details of the Hotfixes.
Uninstall the hotfixes (you may be prompted to restart the client computer).

Once we uninstall the updates, the Restore Files and Folder Wizard functions as expected.

Note: It is advisable to reinstall the update KB3023562 on Windows 8.1 and updates KB3023562 and KB3004375 on Windows 8.0 client once the restoration process completes. Removing a security update will make the client vulnerable. We will update this blog post with a resolution in near future.
