Programs that use DCOM do not work correctly after you install Microsoft Windows Server 2003 Service Pack 1
Article ID: 892500 - View products that this article applies to.
After you install Microsoft Windows Server 2003 Service Pack 1 (SP1), programs that use DCOM do not work correctly. For example, if the server that you installed Windows Server 2003 SP1 on is also a backup server, Veritas Backup Exec 8.6 stops and cannot run backup tasks.
This issue occurs because the default Component Object Model (COM) permissions are changed in Windows Server 2003 SP1. The new COM permissions restrict remote calls that are not authenticated. The COM program may work locally, but the remote calls that are not authenticated fail. By default, only members of the Administrators group have the Remote Activation permission and the Launch permissions. This change prevents user accounts that do not belong to the Administrators group from starting COM components.
