We have a database on a peer-to-peer network. We ugraded the computer that had the data files on it to WindowsXP Pro. Now we are getting this error message on computers running Win98SE: The Microsoft Jet database engine cannot open the file 'GaryShareddocsInvoiceArchives.mdb. It is already opened exclusively by another user, or you need permission to view its data.

How can I get permission? I can open others files on that shared drive, like Word docs. I have never set any security settings on the backoffice database.
