Hi Gaetano, Can you try to have the client running on another machine?. I have a problem when I do that. After I enter the guid to the DCOMConnection1, the Servername is blank in the combo box. In addition, after I entered the computername and change active to true, I received an error message "Access Invalid". If you or anyone know what I did wrong please help. Thanks.
