I had a forums question posted about someone wanting to use Classic ASP and a windows user. All you have to do is run your application pool as network service (not recommended) or a custom user (local or domain). Then make sure the Windows user has rights on the database. If the database is remote, use a domain account. If IIS and SQL are on the same box, you could get away with a local account.
<%
dim conn
dim rs
strConn = “Driver={SQL Server};Server=Server1;Database=Authors;Trusted_Connection=Yes;”
Set cnt = Server.CreateObject(“ADODB.Connection”)
cnt.ConnectionString= strConn
cnt.Open
strSQL = “select * from names”
set rs = cnt.execute(strSQL)
Do while not rs.eof
response.write “Name:” & rs(0)
rs.movenext
Loop
%>
Enjoy,

Pondering Thought 
As far as security goes, how does using Windows Integrated compare to something like this?
conn.ConnectionString = “DSN.DatabaseName”
conn.Open “DSN=DatabaseName;uid=sa;password=;”
The DSN makes it much easier to write out a connection string, but it’s potentially exposing database login credentials, as far as I can tell.

You won’t have to expose a password with Windows Integrated. If you are going to have a username / password. Encrypt your connection string.
