    Hi Manish

    Seems that you have not created a entry in the services file where your WAS is running.

    go to the directory "\WINNT\system32\drivers\etc" where your WAS is running

    open services file and add the following entry at the end

    sapms<3 Letter key word what you have used to create the technical system><tabkey>36<instance number>/tcp<enter key>

    ex: sapmsLAS 3601/tcp

      Hi Manish,

      Do you have a message server defined in your SLD entry? If not, just point to the same system and put PUBLIC in the logon group. Then update your metadata_dest to use the message server.

      Thanks, Erin
