    On the server, if you haven't done so, you need to change the services file.

    Under C:\WINDOWS\system32\drivers\etc

    Make an entry for the system you are trying to connect to.

    For example, if the SID is ABC and the message port is 01, then the entry should look like this.

    sapms<b>ABC</b>        36<b>01</b>/tcp

    After you add the entry, be sure to re-boot the server and try your jCo connection again.

    Regards,
