Let me restate the question: DXBase 2006 works just fine. DXBase 2007 DOES not work. I've looked at all the setting and tried different variations like using Port 7300 in the Hosts file, etc. 2007 can't open the connection and 2006 works like a charm. I've upgraded AR- User to the newest and reloaded DXBase 2007 de K2GN - Larry
