DSN connection runs twice

Question

I have defined System DSN connection "ASPClassic" in ODBC.

After I run the following code in Classic ASP

Set conn=Server.CreateObject("ADODB.Connection")
conn.open "DSN=ASPClassic"

I can see in SQL Server two logon attempts. The first one is a failed attempt for the session user, the second one is succeeded for the admin user using Windows authentication.

The same happens even when I add the admin user to the connection string:

conn.open "DSN=ASPClassic;uid=adminuser"

My AppPool is

No Managed Code, Classic Pipeline, Identity=Network Service, Load User Profile=false

. Why does it happen? Thank You.
