I've got a Windows Server 2008 that is logging me onto a default profile when I login as Administrator. I notice the two following errors in the Event Viewer that appear to be related.
Event 1530, User Profile Service. Windows detected your registry file is still in use by other applications or services
Event 1505, User Profile Service. Windows cannot locate the user's profile but has logged you on with the default profile for the system. DETAIL - Access is denied
Event 6001, Winlogon. The winlogon notification subscriber <Profiles> failed a notification event
