Right now I got time and tried:

I did not found the "administrative templates" in my policies section.

But as it is a 2nd AD server for the domain, I have not done anything to
the afs user account (it is already set with enable DES, no timeout and
accout is sensitive, do not delegate).
On 2 test accounts I enabled the "use krb DES enc types for this account".
But still on a Win7 client added to our domain and the Win 2008R2 server
as only krb5-server I got a error of "KDC has no support for encryption
Any ideas, please?
Maybe the "do not delegate the afs account" is bad?
