that is a very generic error message – honestly, I think the server crashes on start. That could be because of a newer version of db4o dlls (the code is now half a year old and makes quite a bit of assumptions), or because some security issue like inaccessible file, user not authorized to open sockets, etc. Have you checked whether the config file is ok for you, i.e. whether paths are ok?

This server is rudimentary – there is practically no error checking or logging going on, which is a very bad idea when it comes to debugging or even production use. The idea was mainly to show how to get a windows service up and running.
You might want to add some larger `try{ }` blocks and write Exceptions to the log – that might help in finding the error.

Sorry this isn’t too helpful, but there are too many potential errors.

I try your solution, but when I start the server service, windows send me this error:
“the db4oServer service on Local Computer started and then stopped. Some services stop automatically if they have no work to do, for example, the Performance Logs and Alerts service”.
Do you have any ideia of this ???

thank´s
