Answer 1

Seems your application trying to connect SQL Server via windows authentication which usually goes through the user that currently active in application or service account of the application, i'm not sure why the local guest trying to authenticate.

You may want verify the connection string , if no luck, test with SQL Authenticated user that got appropriate access on the SQL Server.

Answer 2

Do verify the connection string in the db properties file or so. It should be like the format: driver=com.microsoft.sqlserver.jdbc.SQLServerDriver url=jdbc:sqlserver://localhost:1433;databaseName=xxxx; user=xxxx pass=xxxx driver=com.microsoft.sqlserver.jdbc.SQLServerDriver url=jdbc:sqlserver://localhost:1433;databaseName=xxxx; user=xxxx pass=xxxx
