What I have done in the past is to make a list of all of the libraries with check boxes next to them on the working machine, then go to the ones that weren't working and set them the same. This won't work if the libraries aren't there. Then you have to find out what program installed the libraries on the good machine and install them on the ones that don't work.
For me, this has occurred most often when the users were accessing a database created with Access 97 while they were running Access 2000. The offending library is almost always Microsft DAO 3.6 Object Library.
Unfortunately, I don't know how to help you get the correct libraries to that many machines. Maybe someone else can enlighten both of us. A+, N+, MCP
