So I have a friend who is running Norton Internet Security version 20.4.0.40. Now I am not sure if this matters, but he got this from Comcast form their site.
Norton is installed on all 4 of his computers (3 Windows 7 and 1 XP). The one system is like the server while the other computers access it.
Every now and then when he leaves them all on, the next day none of the laptops can access the desktop server. Programs will not connect nor can they access any of the shared documents or folders. Rebooting does nothing as well. Only fix is to turn off the firewall and then turn it on and then everything goes back to working fine.
So something in the firewall.
I had him install a small remote program and in the firewall listing it has "Allow" all access, yet when this occurs the firewall blocks it. Again, only turning off the firewall and then turning back on will it then allow me to remote in. His programs; same thing. None of them can talk to the desktop, only turning the firewall off and on then every laptop runs just fine.
Can updates to the firewall cause this? It does not happen often; I think twice in the past 3 months. But it is annoying, especially when all the programs are set up in the firewall to "Allow" full access. We even had one of the program tech support go over all the settings to allow their software to work and it still blocks the traffic until we do the turn off/on.
So any suggestions what we can do?
