Do you have a DAO reference set? That's DAO code. In 2002, you should
be able to run it without a DAO reference, but you have to substitute
late binding and declare the objects as Object rather that DAO.whatever.
I do have ADO code for this, but I don't think I have it on this
machine.

If tdf.Properties(PROPNAME) = "[Auto]" Or _
Err = PROP_NOT_FOUND Then
Says "Constant Expression Required"

It has to be turned off in the properties of the individual table. There
actually is some code in the help file, if you can find it, but here's
my routine. This saves having to open each table in design view and
fiddle with it. If you're using security on your tables, you'll need to
open a workspace using a login and password that has permission to make
design changes to the tables and then open the database using the
secured workspace.

Charlotte -
Where do you turn off subdatasheets?
I'm curious if this will resolve a linked issue I'm having.
Thanks,

Did you remember to turn off subdatasheets on all those tables after you
split the database? You probably need to do it on both front and back
end. That should make a difference in performance with linked tables.

I took a database designed by another individual and split it into a FE
and a BE. Essentially I took all the tables except switchboard, moved
them to a new database and linked them back in. Now some of the larger
reports lock up the system. These reports take seconds to run in the
old database even though they are a couple hundred pages. The symptoms
are the same on all systems. Any ideas?
