Creating WorkFolders fail with: New-SyncShare : Not Found

Currently I am eveluating Microsofts new WorkFolder feature which sounds very promissing to abendon the messy folder redirection feature. So I installed the feature using ServerManager under "File and iSCSI Services" and ran through the wizard.

However when I try to create the the share i receive:

Create sync share failed: The WS-Management service cannot process the request. The service cannot find the resource identified by the resource URI and selectors. 

Next I tried to accomplish the task using powershell:

PS > New-SyncShare WorkFolderTest C:\WorkFolderTest -User "MYDOMAIN\Domain Users"

This fails with the following quite puzzling error:

New-SyncShare : Not found
At line:1 char:1
+ New-SyncShare WorkFolderTest C:\WorkFolderTest -User "MYDOMAIN\Domain Users"
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (Msft_SyncShare:Root/Microsoft/.../Msft_SyncShare) [New-SyncShare], CimE
   xception
    + FullyQualifiedErrorId : HRESULT 0x80041002,New-SyncShare

According to some posts on technet people where able to solve this by previously sharing the folder (C:\WorkFolderTest in my case). However that didn't work for me. What am I doing wrong here? Thanks in advance.

[Addendum]

The application event log shows up the following errors. So this is somehow related to IIS WebCore.

Source:  HostableWebCore
EventID: 2276
Details: The worker process failed to initialize correctly and therefore could not be started.  The data is the error.

EventID: 2269

Also I can't start the "Windows Sync Share" service. It fails with:

Windows could not start the Windows Sync Share on local computer. For more information, review the system event log. If this is a non-microsoft service, contact the service vendor, and refer to service-specific error code **-2147024713**.

System eventlog says:

Source:  Service Control Manager
EventID: 7024
Details: The Windows Sync Share service terminated with the following service-specific error: 
Cannot create a file when that file already exists.

I was able to solve this problem using the most important competence a windows engineer needs to have:

Reboot the system...

Although the Install-WindowsFeature Cmdlet clearly says no reboot is required... it IS required. Solved!!
