WSUS - errors 12072 10032 and 364

Hi

My WSUS server (6.3.9600.16384) on Windows 2012 standard isn't OK, whereas it works fine on April.
- 5 clients are in the console (I use GPO to deploy them and it's OK. On WSUS serveer, I see that this stations needs updates but on this PC ,Windows Update say that nothing is available to update.
- synchronisations (link in the console) is OK with Microsoft but all packages in the WSUS section are with a red cross and when I try to download again it's KO

I Have 3 errors in windows eventviewer :
- First error : id 12072 
The WSUS Content Directory is not accessible 
System.Net.WebException: The remote server returned an error: (404) Internal Server Error. : (404) unreachable [Introuvable].
   à System.Net.HttpWebRequest.GetResponse()
   à Microsoft.UpdateServices.Internal.HealthMonitoring.HmtWebServices.CheckContentDirWebAccess(EventLoggingType type, HealthEventLogger logger)
- Second error : id 10032 
The server is failing to download some updates.
-Third error : id 364
Content file download failed.
Reason: Value does not fall within the expected range.

Destination file : D:WsusContent\A7\8FE59A8CE9E0525D17149882944F243BFD4465A7.cab

It's seems that a "\" is missing inthe Destination file, non ? For information, my WSUS installation is on D: with 3 sub directory : Shares, UpdateServicesPackages, WSUSContent. I have no wsus proxy configured and my wsus server is able to update itself on Windows Update site. Only 1 GB is use on D: wich have 20 GB, subdirectory in wsuscontent are empty.
