I am new to networking so this may be a silly question. I have two machines networked and the only way to get them to see each other is to turn Norton Firewall off on both machines. I have configured the Firewall’s so the addresses of both computers and adapters are noted, I have also turned off the ‘block windows print and file sharing’ option. Still will only see each other when Firewalls are turned off, there is obviously something I’ve missed. By the way once the network is up I can turn the Firewall’s back on with no side effects.
Set up a trusted zone in Norton Firewall and add all computers to it.
Don't just disable Windows Firewall, stop the Windows Firewall Service from running as well (disabling the firewall does not stop the service from running). Set the Windows Firewall srvice to disabled.
A problem I have seen before is with Norton Firewall's port permissions.
Check (and open if necessary) TCP Ports: 139 and 445 and UDP Ports 137 and 138
That should allow general network traffic to go through and for your dcomputers to actually be able to 'see' one another without switching the firewall off.
Just is one of several reasons why I detest Norton Firewall and several similar products...
