Re: LAN server stopped receiving connections
not an ISP problem. the app server and all clients are able to access the internet, the app server can access any of the clients, the clients can access each other but none can access the app server. All ip addresses are 192.168.xxx.xxx so it is an internal problem. A firewall setting (that I can´t find) would explain the behavior but no one has access to change those settings and they dot change themselves. There´s a d-Link DI-524 router and I´ve checked all the permissions on it and they are the same.
Gonna remove all McAfee, deactivate Windows firewall etc and see if that helps.
