Let me see if I understand your problem: -You have the back-end on a network folder. -You have the front-ends on the clients' local drive. -The linked tables from the front-end to the back-end gives you an error. -You mentioned an error in the original post, could you confirm or rewrite what the error exactly says? Some things you can try if you haven't already to hopefully narrow down the root problem: 1. Open and see if you can open the linked tables at all manually inside the table section of the front-end. See if this at least works. 2. Try relinking the tables in the front-end inside one of the user's logins (or a temp user account with the same rights), perhaps the links are off or corrupted. 3. Try recreating a new mdb (i.e. temp.mdb) and link the tables again to see if works. If it works, then there's an issue with the front end. If it doesn't, more likely a connection problem. 4. Browse through Windows explorer to the back-end folder to see if you can even see it. Try opening the back-end file to see if it opens, etc. If it gives you errors, this might give you the hint you need. 5. Try compacting and repairing both files. 6. I have seen cases where linked tables to an Access back-end just does not open, even if you can see the mdb in the network drive. I have had to recreate the folder with the same name in order for it work. If the network folder is located on a client OS (Windows XP) and not on a Server OS (win 2000 server, 2003 server, etc.), it may be the case. 7. Does each client installation of Access fully installed or just the typical installation? Perhaps you made the front-end using a component that is not installed with just a typical installation of Access. Hope this helps.
