Ms-Sql-Hasdbaccess Doesnt Return DB Names

I installed SQL EXPRESS and STUDIO Express (2005) on Win7 VM. then in the Studio Express ran the Northwind installation query with SQL Authentication (sa,123). so I want to run the "ms-sql-hasdbaccess" script to get the northwind DB in the output.

now when I run "nmap -p1433 ms-sql-hasdbaccess --script-args mssql.username=sa,mssql.password=123 10.10.10.135"

the Output is as bellow:

Starting Nmap 6.49BETA4 ( https://nmap.org ) at 2015-12-26 05:38 EST

Nmap scan report for ms-sql-hasdbaccess (202.71.99.194)

Host is up (0.00093s latency).

PORT STATE SERVICE

1433/tcp filtered ms-sql-s

Nmap scan report for 10.10.10.135

Host is up (0.00030s latency).

PORT STATE SERVICE

MAC Address: 00:0C:29:C7:96:87 (VMware)

Nmap done: 2 IP addresses (2 hosts up) scanned in 20.07 seconds

why the output doesnt show the Northwind.
