Error 908 - Connection Refused on remote server

Total Informix newbie here - though I work on Oracle and Sql Server daily. Myself and someone at another company are tasked with getting a db connection going from our network to theirs. Unfortunately, neither of us has any Informix experience. We're both using the IDS 10 free version - at this point we're doing a proof of concept for a project. Both sites are installed on a Windows 2000 server. They are not part of the same domain. Using dbaccess I can connect to my local Informix database without a problem, as he can connect to his. What we can't do is get it configured so that I can connect to his database via dbAccess. We've configured the firewalls so I can ping & VNC into his server. I've set up a Registry entry for SQLHOSTS on his machine: HKLM\\Software\\Informix\\SQLHOSTS\\ol_<their_instance> HOST <their_IP_ADDRESS> PROTOCOL olsoctcp SERVICE Informix66 I tried creating a hosts.equiv file on their server \\windows\\system32\\drivers\\etc with lines for my machine name, my_machine.<domain>.com, my IP address No matter what I do I'm getting an error: 908: Attempt to connect to database server ( <name> ) failed:Connection refused I've read through the books online trying to find a solution, and have googled this 9 ways from Sunday. I'm really stuck here, not sure what else to do. If someone has some advice to offer, or can refer me to a better set of documentation or a book that might help out, it would be greatly appreciated. - Rich W.
