how do i connect to this database from Sql server mgmt studio since there is not use or password in the connection string. i am connecting from a remote machine
When you connect using "Integrated Security", it uses the current Windows credentials of the process - in the case of connecting to SSMS, it will use your current Windows user. If your Windows user has rights to the SQL Server, then you can connect using Intergrated Security.
If you need to connect to the SQL Server using Integrated Security, but as another user, you'll need to do a "Run As..." on SSMS to load it as the different user.
