I've had a lot of experience developing Access ADP files connected to SQL Server directly. I'm very comfortable with it and have found it to be a great combination. I note that the ADP format is now being phased out slowly in favour of linked tables using DSN. I realise this does give me the benfit of also having local tables alongside the linked tables. The thing that concerns me are 'performance issues' with concurrent users etc. In the past I've linked to SQL Server using Access 97 and found it to be very slow even with unbound forms. I'd be pleased to hear of your experiences with Access ACCDB linked tables to SQLServer. Maybe things I should be aware of etc.
Thanks in advance for giving your time to this question.
