    hi there

    pls try to unblock these ports

    If AD and the ADAM instance are installed on the same DC;

        * AD LDAP Port 389
        * AD SSL Port 636
        * AD LDAP Port 50000
        * AD SSL Port 50001

    If AD and the ADAM instance are installed on DIFFERENT DC’s, they both typically use;

        * LDAP Port 389
        * SSL Port 636

    Hi Steviek411,

    why are you bothering with windows firewall? the basic home DSL router has a firewall ten times as good, on a DC, get rid of windows firewall

    otherwise play with this
