I have 2 DC's in my environment.
They are both Win2k3-R2
Both Domain & Forest Functional level are at 2003.
I will like to bring up a Win2k8-R2 DC in my environment as well.
As soon as I start DCpromo I get a prompt that states that installing AD on this DC will prevent NT4.0 clients to log in because of a Cryptography algorithm.
I don't have any NT 4.0 servers in my domain.
I do have XP clients in my domain.
Does this mean that my XP clients will not be able to authenticate to the domain because I'm adding this Domain controller ?
Do I have to install this XP update on all of my XP clients prior to installing this server.
