Another way to check if it is actually the same table being viewed by both PCs is to lock the table on one PC and then try to open on the other PC. Assuming the table name is "MyTable.dbf":

First PC open VFP and execute the following:

USE "M:\Path to Table\MyTable.dbf" IN 0 ALIAS mytable EXCLUSIVE

Now on the second PC, open VFP and execute the same command. If the table is the same table, then the second attempt to open will fail.
