    There would be 3 things to check:

    1) Compare the input in the RFC destination for the successfull and failed system to make sure nothing was missed, especially service or port numbers.

    2) Check the services file on the failed host to see if it has a sapms<SID> entry for the saprouter server

    3) Check the saprouttab to make sure outgoing connections are permitted from this server also.

    Hope this helps.

    ERROR service '?' unknown

    Seems like theres missing entries on your services file. Make sure that all required entries for the gateway are available at the services file on your XI box.

    Regards
