    Hi,

    The error points that service 'sapmsPEC' unknown .

    Can you logon to your backend system go to transaction ST11 and open dev_ms. You will find there the service name and a line like I listen to port xxxx. Please add the same in your WAS server /etc/services file as sapmsPEC xxxx/tcp.

    Do get back if you have any issues.

    Retry !!!!

    Regards,

    Hi,

    may be you should try to connect using the proper router information.

    also it's the message server connection error. Ensure the information you are suppliing is right and proper.

    PUBLIC Group should be also checked.

    Regards and reward if helpful

    And to complete Vijith's Post, if you have a windows service, you should enter the sapmsPCE in this file:

    C:\WINDOWS\system32\drivers\etc\services

      And don't forget to restart your WebAS to take changes in services.etc into account.
