Looks like you can’t connect to the SQL server; is the SQL browser service running and could a firewall block the connection? And are you sure that SQL authentication is configured? The default SQL express instance uses windows authentication.

Sounds like maybe the SQL Browser Service is not running on the target SQL server? Could you check this?

thx you so much 

Really SQL Browser Service is not running just runing services SQL Browser Service

Just to understand, the issue was the SQL Browser service was not running? Your issue is fixed now?
