Hi,

I have an Access database that does'nt open anymore. The error message is
The Microsoft Jet data engine could not find the object MSysDB. MAke shure the object exists and that you spelled its name and the path name correctly.

I tried the db compact utility from Microsoft but without success.
Interesting is that after restoring from tape, the restored copy doesn't work as well. The database worked well at the time the backup was done. I tried even a two weeks old backup; the results were the same.

Thank you.

Dave's right - classic sign of corruption. One of my favorite corruption links here:

I've been already through all of those. There is no explanation why I can't open a db backed up two weeks ago since it worked until few days ago.

The explanation would be "corruption" ... your database file became corrupted somehow, and the reason why could be any number of things (faulty network hardware, corrupt .dll file, etc etc) ... have you tried the methods listed in the links Dave and I provided? If you have, and you cannot recover your data, then you'll either have to (a) contract with a repair service to get your data back or (b) go back to your last known good backup and re-create your data.

Tape backups are notorious for being faulty, especially with Access ... often the software used to make the backups doesn't handle .mdb files very well, and will attempt to backup open files and such, which leads to either incomplete or corrupt backups.

If you can open your tape backup db, have you tried importing all those items in a new, blank database? This often helps ...

The answers didn't help me to fix the database but gave me confidence in deciding to start recovering from historical backups.
