Failed to deploy backup policies on w2k8 r2

Hello

I newly installed Acronis Backup & Recovvery 10 (build 10.0.12497). Everything works well, exept the deployment of the backup policies on windows 2k8 r2 servers. All the others work well, but in w2k8 r2 following log entrys are made:

I checked the Username and Passwort 100 times and connected from the Machine to the Filestore. Everithing works, exept for the deployment. Even a Backup with under same Username works well, if i make the backup plan locally.

please help! Thank you in advance.
