Hello again
I just write here because I found another problem that didn’t allowed me to join computers to the Domain just in case anyone needs it.
In our University all the computers are on the same VLAN with many DHCP Servers and that made that sometimes, not always, the DHCP Client didn’t assign us the correct DNS to be able to join computers to our domain. Finally we decidided to filter via firewall that our clients only can get IP from our DHCP Server.
Thanks for giving me some light to solve our problem and for this nice product.
See you soon
