Hi all, I have the next situation, I have a exchange 2010 organization with a dag and  I done the installation process for exchange 2013 that have a dag and nlb cluster for cas I have ambiguous URL  (internal and external url are the same) in my test environment all works fine. In this moment the clients prompt  for auth. in the internal network. somebody know how to configure Kerberos in exchange 2013?

Are you talking about Outlook clients? Or other type of clients? Kerberos (Windows Authentication), for OWA, is configured in OWA virtual directory properties. Also, your OWA internal URL should be in your local Intranet sites in IE, so that credentials can be delegated. You can also run  the Get-OutlookProvider cmdlet to obtain the global settings from the AutoDiscoverConfig object under the Global Settings object in Active Directory.
