These errors appear when the remote installation task of NAgent or KES with NAgent was created with the Assign package installation in Active Directory group policies option selected.

At the first startup they start under the account specified in the New Task Wizard. If that user has access for creating domain policies and groups, the task will be completed successfully, and "GPO" and "Security Group" with target computers will be created on domain controller.  

When deleting this task, the user credentials entered in the task settings are used. If they are changed, or if the task is being deleted by another user who does not have sufficient rights in the domain, or if the user who created the task has lost its rights, the errors will occur:

Error in EventLog

Failed to delete group policy object 'LDAP://CN={1DEE8F3C-F36F-4FF7-8E18-01C83D482A44},CN=Policies,CN=System,DC=bn,DC=loc': 'System error 0x52E (The user name or password is incorrect.)'

Error in EventLog

Failed to delete group policy object 'LDAP://CN={1DEE8F3C-F36F-4FF7-8E18-01C83D482A44},CN=Policies,CN=System,DC=bn,DC=loc': 'Access is denied.'

To fix it, you need to change the user in the task settings to the one with sufficient rights to delete "GPO" and "Security Group" on domain controller.
