On one of the computers available in the local network we have installed a server created in VB.NET. Network goes through a router to the Internet. There is the possibility to communicate directly with the server, without the information to go through the Internet?

Yes, if it is connected to the same local network as the PC trying to communicate. All you need to do is set up a local socket connection using the computer name or IP address.

If you do not specify that the connection should be via the internet, then it won't.

If you are concerned that the server will be available from the internet to other computers, then you need to configure firewalls at your router and / or server to prevent it.

Well, that's the problem - I do not know how to specify that I do not want to communicate through the Internet!

Then don't prefix is with "www"! :laugh:
If you use the IP address of the PC (probably something starting with "192.", it'll be similar to your PC's LAN IP) then your router / switch will keep it internal. The same if you specify the server name: "\\SERVER92"
Only if it is outside the current network will it start to search the internet.

Then I guess it is something local. Router or antivirus. Because the server can be contacted only if the client (located on the same computer) send the request to the external IP address assigned to router by ISP.
