Why is Impersonate and DefaultCredenti als so slow

I have some web methods that I call from WinForms. When I use anonymous with
impersonate="fa lse" the calls snap right back.

When I change it to Windows Intregrated and use DefaultCredenti als in the
WinForms the web method slows down considerably.

Is this supposed to be the case or I am doing something wrong?

We have an anonymous web application trying to talk to a windows authenticated webservice. This is currently failing with 401 Access Denied errors. We have found that we can get this to work by writing the following code in the web application before calling the webservice: WebServiceInstance.Credentials = new NetworkCredential("username", "password","domain");

I am running an VB.Net app which calls an ASP.Net Web Service and this service accesses SQL Server. The Web Service & SQL Server run on separate Windows 2000 server on the same domain. As we don't use Kerberos, the only means to flow the original user credentials from the VB.Net app right thru to SQL Server is to set the web service object credentials parameter in the VB.Net app. The credentials is created based on the following code...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers.
