TeamViewer is good but it's not the best one in terms of performance. And it's quite pricey if you only need to access several machines for business purposes (remember that TeamViewer is free for home use only, and the cheapest license starts from $850).
Here are other, more flexible alternatives (just google 'remote control software' or 'remote desktop software'):

I use CentraStage and recommend it to you. Not only a possibility to watch what is happening there, but also a possibility to control software and hardware on remote devices and set automatic policies and log events happening in system and so on.
You can read info on it by yourself
One option that some forget is that some of the remote access software programs require someone be on both ends of the computers to make it work. Others will allow you to connect with out someone being at the target computer.
Most are pretty well password controlled. I use logmein and vmc via Hamachi the free vpn.
