Thanks very much. I understand now. I just did not understand
Arvin's two folder thing. I will check out his article.
If you are using RDP (a remote client) each person must log into their own
copy of the front-end. SHARING A FRONT-END IS A RECIPE FOR CORRUPTION, on
any server, even on a terminal server. To avoid that on a terminal server
you place the copy of the front-end into a folder that ONLY that person will
access. So, there's a front-end.mdb in the PW folder, and a front-end.mdb in
the Arvin folder. Arvin logs on ONLY uses the copy of in his folder. If you
go into my folder, I breaka you hands, capish?

Had you described a different situation, I would have given a
different answer. Pardon me for providing an answer for the question
you asked!

I think that you are being overly optimistic. It's not the same at all. It
is somewhat similar, with a lot more work to build, and more work to
implement. It's also orders of magnitude slower to sync more than a few
records for multiple users with any sized update or insert operation.

For Access sized operations (1 to 50 users) I think Terminal Services is the
best solution. Beyond that, it seems to me that an asp/asp.net solution with
a SQL-Server database is more appropriate, since it's likely to need further
scaling anyway.

I was speaking only of UI. Performance would, of course, be
different based on the speed of your connection. It's the web versus
a LAN connection, so I think it's rather odd for you to think it
needs to be noted.

Terminal Services and converting to a browser-based application does
not in any way address the issue of disconnected users, whereas
Sharepoint does. To me, that's more important than anything else,
because I've been dealing with that issue for 13 years, providing
replicated solutions to clients. Sharepoint makes Jet replication
obsolete for all purposes (WTS made it obsolete for anything but
disconnected users). The ease of use and lack of setup required to
use an Access app with Sharepoint is a big win, while still
providing the disconnected user the ability to work and synch.

My wife just told me that one client IS using Terminal Services with
our application without any problems! Thanks.

An odbc connection to a hosted MySql or SQL Server database might be
something to consider.
Cheap. Easy to set up. Don't have to change anything but the links in
the frontend .mdb file.

So I would not have to change any of the code that access the data
(recordsets, dlookups, etc...)? Of course, as long as the table and
field names are the same.

I just installed MySQL Server 5.1 but can't for the life of me figure
out how to access or build a database! I guess I need something else.
