Trying Windows 8 at work and bought new Samsung 700t tablet. Windows 8 works fine with local user (linked to live id) and all our software including Symantec Endpoint 12.1.2. As soon as I join to domain (server 2008) and reboot the live tiles no longer function. Have total reset several times and tried refresh and restore points. My guess is that has to be default behavior of Win 8 GPO compared to 2008 domain GPO. We are very plain on our policies and so far have not found anything on local computer or GPO that can correct issues. Any ideas?
