Hi Experts,
In AD trust properties, there is a box that can be checked off called "The other domain supports Kerberos AES Encryption"...what does this actually do and what is the expected behavior if this option is checked? Please advise.

Thank you!

As I understand it by checking that option, you are adding AES as an accepted encryption cipher which can be used to secure the trust.  I'll let others expand if they have more information

The technet page is here: https://technet.microsoft.com/en-us/library/dd145414.aspx

Essentially, just says whether or not the other domain can use the AES encryption, then uses it.  As long as you are on 2008 or newer and Win7 or newer on workstations you should have no issue.  

This blog post ( https://blogs.technet.microsoft.com/enterprisemobility/2007/11/02/server-2008-and-windows-vista-encryption-better-together/ ) has some more detailed information.
