My isa firewall 2004 cannot access other network

[Guest]

Hello, I have ISA Firewall 2004 installed on WIndows 2003 Server but we have an existing firewall Kerio installed on WIndows 2000 server, we have 4 networks because we have branches my new firewall cannot access the branches.

Have you turned the firewall off before making the connection and then on again once the connection is made -- it should then accept the new connections.
