I have tried to compact a database and get the following error messages, (The Microsoft Jet database engine stopped the process because you and another user are attempting to change the same data at the same time.) and (The Microsoft Jet database engine could not find the object 'MSysCompactError'. Make sure the object exists and that you spell its name and the path name correctly.). This database resides on a network with multiple users. I have a problem compacting the database on the network as well as my C:\ drive. I am using Access 97 and do not have a problem compacting other databases.
