Fix Recommendation

Configure the SharePoint server to use replay-resistant authentication mechanisms for network access to privileged accounts.

If the web application is using Integrated Windows Authentication as the claims provider, perform the following:

Open the Central Administration site, select "Application Management".

On the "Application Management" page, select "Manage Web Applications", select the web application that corresponds to the site reviewed in the "Check" section above, then click the "Authentication Providers" button in the ribbon.

Select the zone corresponding to the web application being reviewed, which will open the "Edit Authentication" dialog in the "Claims Authentication Types" section, select "Negotiate (Kerberos)" in the "Integrated Windows Authentication" dropdown, then click "Save".
