Anthony,
MS SQL Database and SQL Server Management Studio are two different things.
MSSQL Databases is where you create and host your database(s).
Microsoft SQL Server Management Studio Express (SSMSE) is an integrated environment for accessing, configuring, managing, administering, and developing all components of SQL Server.
Based on your MSSQL Server Edition, You can download the MS SQL Management Studio, 2005 Edition at http://bit.ly/3JTPJR 2008 at http://bit.ly/95Xp5n 2008 R2 at http://bit.ly/9nVNKL
“Will it mess with the databases that're already in place? “ NO…Installing the correct Version of SSMSE on the same machine as your database will not cause any trouble.
Once you installed the SSMSE run the SQL Server Management Studio from All Programs in Windows, enter “local” in (Server name), select “SQL Server Authentication” in (Authentication), enter your Database Login and Password, Click on connect.
Once logged in Expand “databases” from the left menu and you will see all your databases.
I hope this will help.
