I check the GUID in the three DC, and they are the same.
All three DC are using the same DNS IP-s on /etc/resolv.conf and in the 
same order:
domain solid-optics.local
search solid-optics.local
nameserver 192.168.10.42 (First DC)
nameserver 192.168.10.41 (Second DC)
nameserver 192.168.10.37 (Third DC)
