How Do I Remote Into My Mac From My Windows Computer?

I don't know if I'm missing some big secret, or if this just hasn't been a priority for Apple. However at my office we use Windows Remote Desktop to login to machines every day all over the country. The problem is my station at the office is a Mac, and when I'm at home and I want to remote into my machine from my Window laptop I'm baffled?! I found all sorts of third party software, tips and tricks to get it done. I'm thinking though, surely there has to be an offical Apple backed means of remoting in to Apple computers from a Windows OS, similar to RDP. Can someone please share with me if this is possible, and if it's not, what's the accepted standard application used to accomplish this?
