What is the difference between 'Windows Authentication' login and 'SQL
login'?

Hi RABMissouri,

Windows authentication - SQL Server uses a special protocol to ask
Windows for the details of the currently logged-in user. If the Windows
user is in the list of allowed logins, the login succeeds wiithout the
user having to enter anything. If the Windows login is not registered as
a SQL Server login, an error message follows.
Advantages: no extra login prompts for user; SQL Server security
benefits from Windows login policies (such as password aging, etc).
Disadvantages: doesn't lend itself for testing; Windows users with admin
rights are automatically logged in as SQL Server admin.

SQL Server login - SQL Server prompts user for loginname and password,
then compares this to list of loginnames and (encrypted) passwords in
system table master..syslogins. On a match, you are logged in.
Advantages: easy when you have to test seecurity for different roles.
Disadvantages: no password expiration, password complexity checks, etc.

I have IIS, MSDE installed on my home computer and I don't log
into windows. So how does 'Windows Authentication' apply in this case?

What version of Windows are yoou using?
