Neat little program similar to Remotely Anywhere ... except it's free for the basic version
I have used it when traveling to connect to my home computer to check forums, email etc
free program is LOGMEIN ... there's several "versions" and you can even try a more powerful version trial period and when it expires it switches to the standard free version (which is all most anyone needs)
basically, it lets you from wherever you are, log in and use your home computer as if you were sitting right at home, the mouse/keyboard you use, act as if they are plugged into your computer at home, the picture on your monitor, is the one at home (it's a window though so it can be minimized)
if you have a webcam and microphone at home, you can even see who's in your house while you are on vacation and what they are stealing and hear one say to the other. "Hey Jim, should we get the silverware tooo ....

You can remotely check your Outlook or work on documents on your home computer etc.
I used to actually manage some MSN servers, (some in California or Washington) by connecting to them from my home in Pasadena, Texas, while on a work computer 60 miles away at a law office in Cleveland, Texas which connected to Logmein, that connected to my home computer through which I was connected to MSN's servers, so I could restart their server or whatever.. It's secure enough. https://secure.logmein.com/" onclick="window.open(this.href);return false;
The computer to be controlled needs to download install the program, (like your home computer) ... then you can connect to it with your account .... from anywhere.
Pedernales Electric Co computer Support uses Remotely Anywhere, which is similar program, but I like Logmein.
My Ex-boss, a lawyer, would work on his Computer on pleadings etc in Cleveland, from his home in Boerne near San Antonio ... telecommuting when he didn't want to drive until the next day. (The downside of me teaching him about it was if I called in sick ... I had to work from home on my computer at work


Anyway, just lettin' y'all know.
I have no affiliation with the company
