File/Storage Errors in Server 2012

Question

Hi
We are running Server 2012 (proper, downloaded from licensing portal) and are using it as an NFS server for some of our VM Ware machines.
Yesterday the NFS storage went offline for approx. 15 minutes, and then came back online.  The following errors are found in Event Viewer, these errors appear to have been happening since 21/08 but this the first time the NFS server has gone offline.
This error is found in the Applications Log:
File Server Resource Manager finished syncing claims from Active Directory and encountered errors during the sync (0x80072030, There is no such object on the server.
).  Please check previous event logs for details.
And is accompanied by this error:
File Server Resource Manager failed to find the claim list 'Global Resource Property List' in Active Directory (ADsPath:
LDAP://mydc.mydomain.local/CN=Global Resource Property List,CN=Resource Property Lists,CN=Claims Configuration,CN=Services,CN=Configuration,DC=mydc,DC=local). Please check that the claims list configured for
this machine in Group Policy exists in Active Directory.
Additionally the following error appears in the System log, but not at the same time as the above:
The Group Policy Client Side Extension Folder Redirection was unable to apply one or more settings because the changes must be processed before system startup or user logon. The system will wait for Group Policy processing to finish completely before
the next startup or logon for this user, and this may result in slow startup and boot performance.
Our PDC is Server 2003 R2, we have a 2008R2 DC and the 2012 server seems to be authenticating with this DC.  There are no errors on that DC.
Any help appreciated.
Many thanks

I thing the following site gives a solution:
It is a schema problem...
Event ID 12339 and 12344: File Server Resource Manager failed to find claim list
Problem: You are running a Windows Server 2012 file server and you see the error messages in your logs every 15 minutes or so.
1) Event ID: 12339
File Server Resource  Manager failed to find the claim list 'Global Resource Property List' in Active Directory (ADsPath: LDAP://dc1.domain.local/CN=Global Resource Property List,CN=Resource Property Lists,CN=Claims Configuration,CN=Services,CN=Configuration,DC=domain,DC=local). 
Please check that the claims list configured for this machine in Group Policy exists in Active Directory.
2) Event ID: 12344
File Server Resource  Manager finished syncing claims from Active Directory and encountered errors during the sync (0x80072030, There is no such object on the server.) Please check previous event logs for details.
Solution: You can either upgrade the Active Directory schema to version 56 (Windows Server 2012) or safely ignore the error messages.
If you can update the schema of your domain. Follow these steps:
1)
log on to Windows Server 2012 as Administrator of your domain
2)
Copy from "support \adprep" in the media of Windows Server 2012 to "c:\"
3)
run this command
c:\adprep\adprep.exe /forestprep
