First of all, the actual title of this article is “How To Remotely Control Your Computer Using Other Computer Through LAN/WiFI Network“, but since it’s too long, I have to cut it down in the middle Okay, here’s the story… since I now have two laptops (well, five actually, but I’ve rarely used the others three), I think it’d be cool if I can use my old Acer 3274WXMi laptop for somekind of download machine. So this morning, I set up my room, placed my Acer on the computer desk, and replace its old location (beside my bed) with my new Sony VAIO FW139EH notebook. Since I’m a lazy guy and I think it’d be stupid to get up from my bed anytime I want to download something, I need to find a way to remotely control that machine.

So here’s exactly what I do:

1. Download TightVNC software.
2. Install TightVNC Server on my Acer and TightVNC Viewer on my Sony.
3. Set the TightVNC Server to run on startup as Windows Service ( Start->Programs->TightVNC->Administration->Install VNC Service) and then start the service manually from command line (since I don’t want to reboot the computer) using ‘net start winvnc’ command. Next I run the Service Helper manually (Start->Programs->TightVNC->Administration->Run Service Helper) to show up TightVNC tray icon.
   
4. The last thing I did on my Acer’s laptop was configuring the TightVNC Server setting (password, etc).
5. On my Sony’s laptop, I run TightVNC Viewer and enter the server’s IP address.
   
6. Done!

Pretty easy, isn’t it? Note that I’m using wireless router on my home, but I heard that TightVNC would work fine under LAN network as well.
