For any No CD to work, you gotta make sure you are using the correct version, and all the game files are available without CD, which meant all available on HD.
For WarCraft III: Reign of Chaos, all game files are already available on HD, so you just need to make sure they, I meant your game version and No CD version, are the same. Newest version should be 1.01b.
First step, make sure you can connect and play on battle net with CD. This will make sure your game version are up-to-date, version 1.01b.
Second step, download the gimpsRus 1.01b virtual crack, using WinRAR 3.00, extract war3.exe and war3.org to your game folder, overwrite existing war3.exe (war3.org is exactly the same as your war3.exe, so no need to backup). Then you are done.
Finally, remove the game CD and start the game as usual.
