Audit a SQL Server Configuration
From SQLServerPedia
BLITZ! One Hour SQL Server TakeoversYou're minding your own business in your corner office - well, no, you're a DBA, so it's just your cubicle - when somebody says, "Did you know about this SQL Server over here?" Suddenly, you have to find out what the server's doing, how it was set up, and whether things are working correctly. In the script below, we will help you tackle unknown servers in 60 minutes to find problems, take an inventory, and set the server up for easier management down the road. For more information about presentations covering this topic, check out Brent Ozar's BLITZ! presentation page. To copy this script, hold your mouse over the script and you'll see a set of icons at the top right of the script. Click on the code-looking icon (the first one) and you'll get a popup window with the raw text of the code. T-SQL Code

Server settings can be made outside of sp_configure too. The easiest way
to check out the service settings are to go into Start, Programs,
Microsoft SQL Server, Configuration Tools, SQL Server Configuration Manager.
Go there now, and drill into SQL Server Services, then right-click on each
service and hit Properties. The advanced properties for the SQL Server
service itself can hide some startup parameters.
Next, check Instant File Initialization. Take a note of the service account
SQL Server is using, and then run secpol.msc. Go into Local Policy, User
Rights Assignment, Perform Volume Maintenance Tasks. Double-click on that
and add the SQL Server service account. This lets SQL Server grow data
files instantly. For more info:

Finally, let's go back to the users and ask questions:
- Can the business operate if this server is down?
- How many employees have to stop working if this server goes down?
- Who should I call when the server goes down?
- Is this server covered by any security or compliance regulations?
We can use their answers to build a good backup & recovery solution.
Is there anything you think should be added here? You can edit this script!
Go to the script's home page:
http://sqlserverpedia.com/wiki/Audit_a_SQL_Server_Configuration
Log into SQLServerPedia (it's free to create an account). After you've
logged in, you'll see an Edit button at the top of the page. Click that,
and you can edit this script right now to add your own contributions!
