A family of Microsoft relational database management systems designed for ease of use.
I did move the BE to SQL Server, took about 3 days, but this is a COMPLEX application that was never designed for it, and performance in some critical areas was terrible. We rolled back. I am not completely giving up on it, but a lot more work would have to be done before this can fly.
My hope is that MSFT networking team finds the problem and fixes it.
NOTE to some posters here: this is not an Access problem; it's a networking problem that Access suffers more from than others.
