All users running XP Sp2 or Vista with Office 2007 and Norton Internet Security. Nobody can connect to the machine with the database. Only if I disable all firewalls. I have opened port 56183 for Outlook.exe on both remote and local machines - send and receive. What process needs to have port 56183 opened? What are the general firewall rules that will allow machines to connect to each other and share the BCM database?
