Cannot Play Warcraft on Local LAN
Warcraft (Dota), is one of the most played LAN games. But sometimes you cannot play the game on LAN.
You are unable to connect to LAN computer to plan on LAN.
When this happens, you can do two things.
1. Re install the game, download the latest installer for Warcraft game and install it.
2. Check your firewall rules, if you have not allowed Warcraft game in the firewall, then you wont be able to see other computers on LAN hosting the game and other computers won't see your hosted game.
Note: When you launch the game for the first time, it will ask you if you want to allow the game in firewall. You need to choose to allow in both "private" and "public" network. This will solve the issue of not seeing others game.
