It means that the connection was not made using Windows-based security
(including the trust relationships from clients to servers that Windows
Authentication requires).

>From the Books On Line glossary:

trusted connection
A Windows network connection that can be opened only by users who have
been authenticated by the network. The users are identified by their
Windows login ID and do not have to enter a separate SQL Server login
ID.

Windows Authentication
One of two mechanisms for validating attempts to connect to instances of
SQL Server. Users are identified by their Windows user or group when
they connect. Windows Authentication is the most secure mechanism for
connecting to SQL Server.
