First up, is your modem still in there. If so, plug it into your telephone outlet and go into your Control Panel via "Start>Settings".

>Internet Options>Connections>CHECK "always dial my default connection">Apply.

This, if your administrator hasn't deleted the dial up settings, should give you a direct line and a dial up connection via your ISP.

For the rest of your program to work on DSL you will need to change the setting back to "Never dial a connection".

Next, I would be looking for two things. A better (updated?) program and an administrator that knows your business needs.

Finally, get a real technician in there to set up the program to function purely on DSL. Whoever is administering your systems (sorry if he/she are friends), fire them. They haven't a clue what they're doing.

Your job is to do whatever it is you do. Give the computer tech jobs to real techies, mate. Find a good one, your business will run much smoother.

Good luck.
