Hi Jaime,
The way we handle things similar to this is run IIS on the remote machine and call the remote file with the Inet control by MS. The inet control will allow you to post data to a remote file and get the response. You would then need to read the response.

Don't know if this is specifically what you need, but it may lead you in a good direction. Also consider one of the 3rd party TCP/IP contols available.

PS. here is the particular object code to create the object

THIS.MSInet = CreateObject("inetctls.inet.1")
