I am trying to connect to FSUIPC from a web page under IIS. Security privs were dropped in case that was a problem, and I am using the FSUIPCConnection dll file I got from this site to make the interface to FSUIPC under FS2004. When I try to connect using an aspx (C#) web page, it throws a "FSUIPC is not running" exception when FS is indeed running. Any ideas? Could it be that the server enviornment doesnt allow memory access to programs running? I have not yet registered FSUIPC, could that be the problem perhaps?
