Active Directory Backup Is Canceled If a File Is Busy

The process of backing up Active Directory Backup is canceled if a busy file is encountered. The Active Directory backup process returns error code 0XC8000408 (JET_errFileAccessDenied) and you must start the backup process again from the beginning.

The DSBackupOpenFile function (one of the Active Directory backup functions) returns error code 0XC8000408 (JET_errFileAccessDenied) if it encounters a busy file. Later calls to DSBackupOpenFile return error code 0xC8000208 (JET_errNoBackup), and you must start the backup process again from the beginning. The most common cause of this problem is an antivirus program that holds a file open. After you apply the hotfix that is described in this article, DSBackupOpenFile retries the open action for a maximum of 10 seconds if the function encounters an "access denied" error. If you still experience the problem after you install the hotfix, contact Microsoft for more help.
