Hi!! I develop an Intranet Web Application and I use the Integrated Authentication, ASP.NET 2.0 and IIS 6.0, but I'd like to enable the function to change the connected user (like Sharepoint)... Which is the method to do this?? I use this code: Response.Status = "401 Unauthorized" Response.AddHeader("WWW-Authenticate", "NTLM") to ask the user credential, but after the use insert the correct credential I can't redirect to Home page... Any Idea? Thanks. Mino
