Remote Assistance

I am looking into some type of free remote assistance program outside of Windows Remote Assistance. I know of RealVNC and the like, but wanted to get some feedback.

My only main needs is the ability to remotely install it via Group Policy or another means, requires a password to connect, does not require the end use to accept.

Any ideas?

Check out the following instructions for remotely installing VNC. Combine these together in a script and you should be ready to roll it out.
