ODBC Linked tables / MS Access Linked Tables

Currently we have an Access database that has ODBC linked tables to our software (Greentree). Linked table manager shows as " DSN=Greentree; "
It seems every time I want to run a query using these linked tables a popup window entitled "Jade Connect" pops up requesting username / password, which we provide, and it then takes age's to run.
I would like to find a way to set up another Database, with Tables that are refreshed either manually in the morning, or overnight via a script, and not linked in this manner, so we can run a query without continously loggin in, and taking so long to run.

Any help / Advice is gratefull.

Your first goal should be to figure out:
1. How to save the password.
(There should be a screen somewhere in the ODBC setup that has an option to "Save/Store" Password)
2. Find out why the performance is so slow.
(Old ODBC Drivers, slow network performance, &ect)

If you can get these things figured out, then a "refresh" system would not be needed.

The system you are asking for, while it sounds straightforward, can end up being fairly complex.
Because you may have to and rename the linked tables, then run make table queries to make real static tables from the linked tables with the original table names.
You would have to keep track of which tables you are using and the date/time of the last refresh, in case someone forgets to do the refresh.
You may also need a Rollback system if the refresh fails.
Finally, you will need a fairly good background in VBA coding to take any generic code and customize it.

Not impossible, ...but probably avoidable if you instead fixed the Password and Performance issues first.
