LOGSHIPPING: Error: SLS_LogShipping_Add_Cleanup_Job failed (32204)

When setting up logshipping, received error:
"Error: SLS_LogShipping_Add_Cleanup_Job failed"

SQL Server service account and SQL Server Agent service account  must have sysadmin permission on accessing the publisher's and vice versa

Verify that  the accounts starting  SQL Server service and SQL Server Agent service have the sysadmin permission  to access not only the Publisher server, but also the  Subscriber SQL Server.   The simplest  method is to use a domain account having sysadmin rights on both servers.   Then  re-access the  log shipping set up..
