Hi guys We are having issues joining a Win 2008 R2 server to the domain. There is a firewall between the 2. What are the ports that needs to be opened for the join to be succesfull? I can ping the server from my domain and from the server , if i use FQDN, i can ping the DC's needed to join the domain PS: What can i do to confirm that it is indeed the firewall blocking the communication and not something else maybe?
