My users want to have both Web and Access Front-ends to an Access Back-end 
database.

I've tested this and when a bound form in the Access FE is open (which 
will be the case 99% of the time) I cannot open the connection to the 
database in ASP, getting the following error message "Microsoft JET 
Database Engine (0x80004005)  Could not
use ''; file already in use."

Is it possible to have the ASP and Access FEs working simultaneously to 
the same back-end Access database?

Thanks
Paul

Um... something doesn't sound right here.  I'm currently running an ASP 
application from an IIS5 server with an Access 97 backend.  For kicks, I 
built a bound form and played with it, then launched the web app without 
any problems.  What you might do is check to see if in Access options you 
have the 'open database exclusively' flag checked.
