>Yes I have tables in the development mode that have dummy data in them and tables in production with real data in them. But when I try and use the exe in production I can't open up the tables and I can in development. Why wouldn't the tables not be marked to the database in production, if I have no such problems in development? Thanks,

It sounds like the table on the network has lost its link to the DBC. For each table that belongs to a DBC, there is a place in the table's header that stores a backlink to the DBC (so VFP knows which DBC the table belongs to).

From the VFP command window, what happens when you open the table on the network?
