I was looking at the Microsoft website and it stated that the limit of Concurrent Users to an accdb file is 255. If memory serves me correctly, it was recommended to only have 20 to 25 users connect to an mdb file (only several years ago).
Are these rules for split DB's vs. many users connecting to one file? What if the connection is an ODBC connection and not linked tables? Would linking 500 tables via an FE count the same as an FE linking to 2 tables?
What are some of your experiences with pushing the limits of Concurrent users?
