We're running Veritas Backup Exec 8.6 on Windows 2000. A few days ago Backup Exec just stopped running and scheduling jobs. We backup exchange and file servers. All the jobs in the queue are all showing a "missed" status, and Backup Exec doesn't re-schedule the job like it used to do. If I tell a job to "run now" it just schedules it and does nothing.
The tape loader seems to be working fine. I can load/unload tapes, perform maintenance, etc through the loader's on-board display.
We haven't changed, upgraded or reinstalled anything. The error I found in the event log says "Unable to load file ESEBCLI2.DLL" but we're using Exchange 5.5, and as I understand it, that DLL is only needed for later versions of Exchange.
Another error I found in the log says "A service specific error has occurred. Backup Exec error: 6 SelfServiceStatus." I checked online briefly but was unable to find anything on this error.
Anybody have any ideas?
