cann't connect to tamino

I use tamino4.1.1,the web server is IIS;
I set authentication of IIS to “BASE” and tamino to “tamino”,I have a same user and password in tamino and Windows system. The code bellow is used to connect to tamino:

TaminoConnection conn=new TaminoConnection(
http://localhost/tamino/mydb”,
new TaminoUserInfo(“administrator”,“admin”));
conn.Open(TaminoConnectionMode.AutoCommit);

but error 401 is returned by web server?
How can I connect to it?

Hi,

Could you provide a full stack trace of the exception you receive? I have a suspicion of what it might be and a stack trace could confirm this.

Cheers, Mark

thank you. Here is the stack trace:
