The asp_db_connection file is used when workstations have a problem trying to start the network version of TaxCalc. The file consists of encrypted connection details to allow the workstation to be able to start the program even if they dont get a response from the Acorah Discovery Service running on the server.
This file tells the workstation where the database is.

If you have multiple users of TaxCalc within the office and you each work on separate clients, you can associate the relevant clients to a specific user within the hub.

COM (Common Object Model) add-ins are used to extend the functionality of Office applications. They are normally used to automate certain tasks in response to an action (for instance clicking on a toolbar icon, or opening/closing documents or worksheets).

A Virtual Private network (also known as a VPN) allows the user to create a secure tunnel from their location to a specified location elsewhere on the internet.

This is most commonly utilised when users wish to connect to a remote site to access sensitive data as if they were on the network/PC at the far end.

TaxCalc users commonly utilise a VPN to run TaxCalc while away from the office. The remote machine initiates a VPN connection to a device on the network (most commonly the router or server) and establishes a secure end to end "tunnel". The remote user could then use the network copy of TaxCalc as any other PC on the network at the far end could (subject to bandwidth limitations).
