I am attempting to back up the default domain controller policy and got this error. Event Type: Error Event Source: Group Policy Management Event Category: None Event ID: 2004 Description: Backup of GPO failed. Error [Invalid pointer]. Details - Source GPO: DisplayName: Default Domain Controllers Policy ID: {6AC1786C-016F-11D2-945F-00C04fB984F9} Domain: ourdomain.domain Backup: Directory: C:\GPOBackup Instance : {0DFA9DE2-7CE5-4B23-B290-EA02396EAA06} Comment : Any ideas what caused this and what I can do to resolve this? I tried to run the BackupGPO.wsf in the GPMC\Scripts folder and received the same message. I read out on a page that another person was having the same problem and they claimed to have resolved this after finding an account listed in the Log on as a service right that had the same name as a built in account (SA). ??? Any help that can be offered is greatly appreciated. Thanks, Francis
