I keep getting "Access Denied" when trying to open the "SECURITY_DESCRIPTOR" stream and the "OBJECT_ID" stream for restore, even though my process holds the SeRestorePrivilege. I had tried opening the file handle with the ACCESS_SYSTEM_SECURITY flag, and the WRITE_DAC and WRITE_OWNER flags, but nothing works. Am I using the wrong names for those streams? What else could I be doing wrong?
