SYSVOL Permissions Issue On 2012 Datacenter

Hi Experts

We have just upgraded our Active Directory Servers to 2012 Datacenter, AD, DNS & DHCP are working fine, but we are having some issues with Group Policy as follows:

We have a GPO that redirects the users doccuments and desktop to a network share but it isnt working, when I run GPRESULT /R it show that that policy has been applied, but when saving a file to the desktop it saves it on the C:
All our Users are running Win7 Enterprise

The second issue is when we change a GPO, and view the "Status" we get the following message:

The SYSVOL permissions for one or more GPOs on this domain controller are not in sync with the permissions for the GPOs on the baseline domain controller.

Any help is greatly appreciated

Thanks

Jon
