Hello all, <br><br>I investing the possibility of changing our approach to N-Tier. <br><br>I tried to make a trial project using DCOM, but was not successful. <br><br>On the server, I tried to create an instance of the class on the client and recieved the error of COGETOBJECT failed,<br>Server Execution Error. <br><br>On the client, I tried to use the CreateObject function the create an instance through the server and I got an automation error. The communication between the two is fine, ping, telnet work. <br><br>When I try to create a local instance of the ActiveX EXE on both the server and on the client. I succeed.<br><br>Any help would be appreciated.<br><br>Thank you in advance.<br><br>Ed
