I really recommend using a real DBMS rather than Paradox tables.  Your reliability, even on a single user app, goes way up.  When sharing, your reliability and speed are improved by significant factors.

Interbase is cheap, its open-source variant (firebird) is free, MySQL is Free, and so on.

It's a bit more complex to set up, but it pays for itself the first time you don't have to rebuild your indexes as you often need to with Paradox.

You must use TSession - and be sure that the Net file is located on a drive visible to both computers.

Sometimes it's necessary to remove older Paradox.lck/Pdoxusr.lck if already exist. Normally the files is deleted automatically, but if the program crash they won't be deleted.
