- You use Integrated Windows authentication together with IIS 7.0.
- You use the Kerberos authentication protocol to authenticate the user on the Web site.
This behavior differs from the behavior in IIS 5.0. In IIS 5.0, a client that is authenticated by the Kerberos protocol after an initial HTTP request stays authenticated during the HTTP keep-alive session.
- Click Start, click Run, type cmd, and then click OK.
- At the command prompt, type the following commands, and then press ENTER:cd %SystemRoot%\System32\inetsrv
appcmd set config /section:windowsAuthentication /authPersistNonNTLM:true
For more information about HTTP keep-alive sessions, visit the following Internet Engineering Task Force (IETF) Web site:authPersistNonNTLM configuration property in IIS 7.0 replaces the EnableKerbAuthPersist registry key that is used in IIS 6.0.
