ChangeDB error

ChangeDB error

Hi All,
Following the pmp-help.pdf, I'm trying to change the default DB from Postgres to Sql Server
My server is a Master (I want to implement the HA) windows server 2012 r2, with sql server 2012 express edition, and the db owner is (then I will change it) the domain administrator
I have created the certificate, and save it on the PMP store
Launching the db change configuration , after the procedure ends, on the log file I have this error

com.adventnet.passtrix.utils.PMPChangeDBServer validateDataBase
INFO: network error IOException: Connection Refused: connect

I'm using windows authentication and default encryption key
I have created the PassTrix DB on sql server

The pmp service is up and now starts with the domain administrator

Have you any Idea?

Regards
