Firewalls can block ISIM Server installation
Stop all firewalls before you initiate the product installation and configuration to prevent problems.
A firewall on the computer where ISIM Server is being installed might cause the installation to fail. For example, the middleware configuration component initiates LDAP commands. The firewall blocks the LDAP port, that is, port 389, which blocks LDAP commands from running. LDAP commands include ldapsearch and ldapadd.
