1. Create a new database. Using case sensitive collation (collation name ending with '_CS_AS') is recommended and and is mandatory for the certain functionality (like using non-Windows build agents).

2. Create TeamCity user and ensure that this user is the owner of the database (grant the user dbo rights). This requirement is necessary because the user needs to have ability to modify the database schema.

3. Download and unpack http://www.microsoft.com/en-us/download/details.aspx?displaylang=en&id=11774

4. Copy sqljdbc4.jar to <TeamCity Data Directory>/lib/jdbc

5. For integrated security support copy auth/x86/sqljdbc_auth.dll (since TeamCity runs as a 32-bit process) to location in PATH, e.g. C:\Windows\. Note: C:\Windows\System32\ in a 64-bit Explorer contains 64-bit libraries and it's not what 32-bit process like TeamCity sees.

6. Set up \config\database.properties

   connectionUrl=jdbc:sqlserver://localhost\sqlexpress;databaseName=TeamCity;integratedSecurity=true
