Cannot create partitioned snapshot job. A job already exists for publication '%1!s!' that uses the values you specified for the @suser_sname and/or @host_name parameters of sp_adddynamicsnapshot_job. If the job that already exists is not working correctly, use sp_dropdynamicsnapshot_job to drop it and create a new one using sp_adddynamicsnapshot_job.
