Connection SQL Server 2012 via Windows service

Question

I created a windows service for monitoring to send data (OS info, proc, ram etc) to my SQL Server database and it works fine on my computer. I already installed the service in another machine that has SQL Server and it can connect to mydatabase successfully but when the service runs it appear those error in service log.

This is my connection string

CONNECTION_STRING = "Server=*******\\SQLEXPRESS;Database=Parc_informatique; User Id=tsi;password=******;";

Also the service run as local user

You should either run the service as a user who has access to your SQL database and use a connection string with a trusted connection. Or you should update your connection string with a username and password that has access to your database. — quaabaam
Does this answer your question? SQL Server returns error "Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'." in Windows application — quaabaam
I have a connection string with username , password and ,I can connect to my database through SQl server management in the other machine but the service doesn't work and that what I find in log of the windows service — rayen

I solved it by adding Integrated Security=False to the connection string like this

CONNECTION_STRING = "Server=*\SQLEXPRESS;Database=Parc_informatique; User Id=tsi;password=;Integrated Security=False;"
