How to connect Android mobile with PC using Teamviewer app using Wifi connection without internet?

I know we can use the teamviewer app to connect to PC using internet connection for remote desktop connection. But I want to know if it is possible to connect the PC with Phone using the Wifi connection. Both the Android device and the computer are on the same network, and I want to connect them directly, without needing internet access. Teamviewer has an option to connect to PC's within same LAN. But these settings needs to be configured in the systems to be communicated. I don't know how to change these settings in my phone. Does anyone know how to achieve this or know any better free app that allows remote desktop connection using wifi, without needing internet access?
