LoadRunner does not currently support Microsoft Distributed Password Authentication (DPA)

To determine if DPA is being used in the generation log look at the header in the Server response to the initial GET. The following is an example server response:

HTTP/1.1 401 Access Denied\r\n

Server: Microsoft-IIS/5.0\r\n

Content-length: 616\r\n

Proxy-Connection: Keep-Alive\r\n

Connection: Keep-Alive\r\n
