Roland,

As a suggestion, would it not be better to have a multithreaded application?

There would be one config file (or registry hive etc), containing your
different configurations. When the service starts, it would first load the
config into a queue, then create N threads (where N is the number of
databases you want to read from). Each thread would then take the next
configuration block of the queue, and process to copy that database.

This would mean that you could easily stop and start the threads via a
global "running" flag which you simply set to false. Similarly, starting the
process would kick off all the threads to do your work.

It would be one application, installed at one location, running as one
process with many threads.

If you need more help with ideas for implementing this, let me know.

hope that helps and good luck.

Daniel.
