Hi,
I have the same problem. I tried also the following:
1. Stopped all services (including the MSDE engine)
2. Renamed the old Catalogs folder, created a new empty one
3. Restarted all the services
4. Tried to catalog a tape
The catalog job failed with the same error as in the first post in this thread. The new Catalogs folder remained empty (no database, no index file) - during the catalog operation I could see BE creating temporary files in that directory (I think they were empty), which it automatically deleted in the end. I checked permissions, everything is ok (services run in local administrators group, which has full access, inheritance enabled). Version is 10 rel. 5484.
Any other ideeas?
King regards,
Dragos
