After we upgarded to BE9.0 and patched our 5.1 server to sp5, I have
had
intermittent problems (which are getting worse) with Backup Exec.

E.G I got a backup yesterday morning (after I came in to work very
early to
restart the server before anyone got here) and then to ensure that the

backup would happen last night (like normal), I restarted the server
at
lunchtime.

The backup didn't work, I go this error in the log file ERROR - NDMP
Error
NDMP_NO_DEVICE_ERR (16).

Then I unloaded BE and it doesn't reload, it jsut gives me errors
1050:
No devices found during installation.
The device driver load was unsuccessful. etc.

If anyone else has had this problem and knows the solution, I would be
very
grateful.

Emily.
