I have remote office location which i need to join to our main domain. I accually joined pc to the domain, but when i try to login to that domain it says that "The system cannot log you in because domain "mydomain" not available. On my firewall i allowed these ports:
AD replication, DNS, File replication service, Global Catalog LDAP, Kerberos (tcp/udp), LDAP(tcp/udp), NTP. And i still cannot login with the AD account. What am i missing here?
