I have developed an application in vb.net with OleDb MS Database.
I want establish LAN connectivity between 3 pc by this Application.
So is it possible to run one PC as server and in another 2 pc , one can enter data?

maybe you can do that if your modem have many ports shared the internet connection then used that link above, it will works.

You need a router connecting 3 PCs, then open a socket and listen to it and other PCs can send data to the socket.
