Report Server failing to update from Access Database

[pabeader]

I can manually update from within the desktop app but if I try to update on the server I get an error message.

Any ideas would be wonderful.  

I added a service user account and get a good connection when I test it.

Any chance you can replace the Access db with a real database?

Nope.  Different department and the LOVE access.

did you make the lock file writable ?
