Two Windows clients are disconnecting just from Internet
-
Frequently I have 2 clients (Windows) that get disconnected just from Internet, not from the intranet, in other words, these 2 clients stop to access the Internet, but still can transfer or access another clients in the Intranet. In the meantime, the other clients are using the Internet normally. I have know idea what can be and how to start a troubleshooting.
All the clients are set with fixed IP in the DHCP server.

So when you mean they can no longer resolve stuff or can not access public IPs and resolve just fine? My guess would be your using multiple dns servers one that can resolve public, and other than can not - like your AD server maybe?
On these clients try and resolve www.google.com via either ping? Or nslookup or dig or whatever your fav dns query tool is. Does that not work? What dns is pointing to - nslookup or dig will tell you that.
If they do resolve try pinging something on the outside say 8.8.8.8 does that not work?

The machines can not access public IPs, but resolve just fine… I still can ping any URL, while no page are showing, giving timeout error. Just the pfSense is the DNS Server.

I can ping and resolve google.com and 8.8.8.8 or anything outside…. Nslookup return the pfSense IP.
