Sounds like your connecting to the same server.

1) Check the MultiServer Connect and verify its propery setting expresssions is ServerName @[User::SRV_Conn]

2) Now check Populate ADO Variable properties.

The Result Set should be

Result Name 0

Variable Name User::SQL_RS

This variable was my default value. I should of documented that it should be selected.

3) Run this query to confirm the server names in the table

SELECT RTRIM(Server) AS servername

FROM SSIS_ServerList

WHERE (Skip_SQL_Overview is null or Skip_SQL_Overview = 'FALSE')

ORDER BY 1

Let me know how it goes
