Windows attempted to read the file \\ct.mydomain.com\sysvol\ct.mydomain.com\Policies\{31B2F340-016D-11D2-945F-00C04FB984F9}\gpt.ini from a domain controller and was not successful. Group Policy settings may not be applied until this event is resolved. This issue may be transient and could be caused by one or more of the following:
