Hi Andrew.
Ok
I no longer have the replicating DC setup so I do not get the PANIC 
error message any longer. I am now working on a single DC which was 
working with the beta6 and beta7 git releases but which now fails with a 
talloc error. Neither does it create arcfour keys when I create a new 
spn and export the keytab.

I'll start another thread.
Cheers,
Steve
