vco 5.1 loses database configuration when the vco configuration service is restarted

Hi,

We are configuring our server now, everything works fine at the firts time configuration, but, the problem comes when we restart de vco configuration service at the vco server, for any reason we must to do it, just because we have made a new plug-in configuration or just simulating a server failure or server restart. every configuration data remains except for the database configuration information which is lost and then the vco service try to use default data but this obviously fails. by the way we have configured (in right way) the ODBC driver for the Database connection on the vco server, proof of that is that at the first time configuration everything works fine. We just dont know what to do. can you help us, please ?
