SYMPTOMSWhen you install the VERITAS NetBackup 4.5 backup program,
it does not detect your tape drive during the device configuration portion of
Setup. When it scans for installed devices, you receive a result of "No devices
detected". CAUSEThis issue occurs because the VERITAS NetBackup program
tries to send a request to the logical unit number (LUN) of the tape device and
have it forwarded to the storage adapter (typically, a SCSI adapter), instead
of sending the request directly to the storage adapter that enumerates the tape
device. In Windows Server
2003, this privileged call by the NetBackup program is denied.RESOLUTIONTo resolve this issue, contact VERITAS to obtain a possible
update for the NetBackup 4.5 program. For information about how to obtain

STATUS
This behavior is by design.MORE INFORMATIONIn earlier versions of Windows, if a program sent a request
to the LUN of a device, the device would forward the request to its adapter.
Because the adapter and the LUN have different security permissions (the
adapter has administrator-only permissions), this behavior permits a
user or program with restricted access to the computer to make a privileged call
to the storage adapter. The third-party products that are discussed in this article are
