We have a problem with our backup. After the installation of Microsoft SQL Serveur Express 2005 on our Windows Server 2003, Backup Exec 10.0.5484 put an error, witch is described on one of the joined file. Backup Exec makes no more backup at all. We also see a GPO error. We don't know if this problem is liked with Backup Exec (see also joined file). Note: as we have a french server, some items are in French, but we translated the most possible of them.
