I am trying to figure out which ports need to be opened on our firewall in order for a remote site to add their Windows XP Pro machines to the Windows Server 2003 domain. I have port 445 TCP open for MS-DS, and then I have read that port 389/UDP for LDAP ping, 88/TCP&UDP Kerberos authentication, and MS-DS 445/UDP needs to be open also, is this correct? Are there any other ports that I am missing? I am assigning max points to this as I need the information right away.
Thanks in advance,
